A 10 Fact Salute to Casey Kasem

Original image

Earlier this week the venerable Kemal Amin Kasem, better known to radio listeners as Casey Kasem, announced that he was stepping down from his weekly countdown show. The Detroit native has done a lot of other voiceover work in addition to small acting roles in his 77 years, but he'll no doubt always be remembered as the voice of American Top 40. Here are 10 quick Casey facts everyone should know, countdown-style:

10.  Casey's relationship with Scooby-Doo (and Why he Left the Franchise!)

Believe it or not, Casey had provided the voice of "Shaggy" on Scooby-Doo, Where Are You? from the show's inception in 1969 but left the series in 1995 after a beef over a Burger King commercial. Kasem had become a vegan and could not in good conscience promote the consumption of hamburgers. He came back to the fold in 2002 when producers made the Shaggy character a strict vegetarian.

9.  What band's popularity did Casey woefully misjudge?

When introducing "Pride (In the Name of Love)," U2's first U.S. top 40 single, Casey began reading a lengthy introduction/explanation: "That's the letter "˜U' and the numeral two"¦.The four-man band features Adam Clayton on bass, Larry Mullen on drums, Dave Evans, nicknamed "˜The Edge', on"¦ this is bull----!  Nobody cares! These guys are from England, who gives a (bad word)?!" For the record: The band actually hails from Ireland, and they did go on to sell a few million records in the years to come.

8. Have any Casey mistakes made it to the actual American Top 40 broadcast?

A couple. For example, during the first hour of a January 1976 broadcast, Casey mentioned that Simon and Garfunkel's "The Sounds of Silence" was the number one song exactly 10 years ago. Then, during the second hour of the show he said the same thing about the Beatles' "We Can Work It Out." He also related a back-story about Paul Revere and the Raiders' "Indian Reservation" that later turned out to be a complete fabrication made up by the song's composer, John D. Loudermilk.

7. When did AT40 debut?

Casey first counted "˜em down on July 4, 1970. The show was broadcast on only a handful of stations at the time, and listeners had to wait an anxious three hours before finding out that the number one hit in the nation that week was "Mama Told Me (Not to Come)" by Three Dog Night.

6. What was the first Long Distance Dedication?

The LDD debuted in August 1978. A man wrote Casey requesting a special song for his girlfriend, Desiree, who was moving to Germany to live with her family on an Air Force Base. The bereft boyfriend's song request? "Desiree" by Neil Diamond, natch.

5. What is Casey's connection to The Price is Right?

Picture 12Casey and his wife Jean (you may remember her as squeaky-voiced "Loretta Tortelli" on Cheers) are the co-owners of the Little Miss Liberty Round Crib Company. Their designer baby cribs (named after their daughter Liberty) frequently pop up as prizes on America's favorite game show. If you never manage to get into a Showcase Showdown but still have a hankering for a $700 baby bed, Little Miss Liberty Cribs are available in retail shops as well.

4. What song made it to number one without Casey ever mentioning its title during its ascent up the chart?

That honor goes to George Michael's 1987 hit "I Want Your Sex." Even though he was very liberal in his politics, Casey was conservative when it came to AT40 and he just couldn't bring himself to articulate this title over the air. Instead he simply announced something along the lines of "here's the latest hit by George Michael" each week the tune remained in the Top 40. (Luckily Shadoe Stevens was hosting the show by the time 2 Live Crew's "Me So Horny" hit the charts.)

3. Wait a minute "“ Casey wouldn't say "I Want Your Sex"? Isn't this the same guy who cussed out U2?

Yes, but he didn't do that over the air. That little tirade was an outtake that somehow leaked out of the studio. And whatever his objections may have been to the title of George Michael's song, he still dutifully announced Rod Stewart's "Ain't Love a Bitch" during the late Spring of 1979.

 2.  How did radio stations around the world get AT40 "“ was it via satellite feed or what?

During the Casey era, each installment of AT40 was pressed on to vinyl LP records (usually four per show) and mass-mailed to subscribing radio stations. Every now and then listeners in certain markets would hear a "skip" during the show caused by a scratch in the record.

 1.  What's the deal with the infamous "Snuggles" rant?

Picture 1During the September 14, 1985, countdown the Pointer Sisters lively hit "Dare Me" had just finished playing when Casey began reading a Long Distance Dedication. A listener had written a poignant story about the death of his dog, Snuggles, and had requested that Casey play the Henry Gross song "Shannon" in tribute. What listeners didn't know was that it took several "takes" to get that segment recorded properly, because Casey had trouble getting into the properly somber mood after an up-tempo song. The tape was still rolling when he launched into a profanity-laced tirade directed at his engineer and producer. That rant didn't make it on the air until years later when it became a staple of morning radio drive-time shows looking for a laugh. You can hear it here, but be forewarned "“ the language is not suitable for the workplace, young children, grandma or family pets.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

10 Facts About the Tomb of the Unknown Soldier
May 29, 2017

Library of Congress

On Veterans Day, 1921, President Warren G. Harding presided over an interment ceremony at Arlington National Cemetery for an unknown soldier who died during World War I. Since then, three more soldiers have been added to the Tomb of the Unknowns (also known as the Tomb of the Unknown Soldier) memorial—and one has been disinterred. Below, a few things you might not know about the historic site and the rituals that surround it.

To ensure a truly random selection, four unknown soldiers were exhumed from four different WWI American cemeteries in France. U.S. Army Sgt. Edward F. Younger, who was wounded in combat and received the Distinguished Service Medal, was chosen to select a soldier for burial at the Tomb of the Unknowns in Arlington. After the four identical caskets were lined up for his inspection, Younger chose the third casket from the left by placing a spray of white roses on it. The chosen soldier was transported to the U.S. on the USS Olympia, while the other three were reburied at Meuse Argonne American Cemetery in France.


One had served in the European Theater and the other served in the Pacific Theater. The Navy’s only active-duty Medal of Honor recipient, Hospitalman 1st Class William R. Charette, chose one of the identical caskets to go on to Arlington. The other was given a burial at sea.

The soldiers were disinterred from the National Cemetery of the Pacific in Hawaii. This time, Army Master Sgt. Ned Lyle was the one to choose the casket. Along with the unknown soldier from WWII, the unknown Korean War soldier lay in the Capitol Rotunda from May 28 to May 30, 1958.


Medal of Honor recipient U.S. Marine Corps Sgt. Maj. Allan Jay Kellogg, Jr., selected the Vietnam War representative during a ceremony at Pearl Harbor.

Thanks to advances in mitochondrial DNA testing, scientists were eventually able to identify the remains of the Vietnam War soldier. On May 14, 1998, the remains were exhumed and tested, revealing the “unknown” soldier to be Air Force 1st Lt. Michael Joseph Blassie (pictured). Blassie was shot down near An Loc, Vietnam, in 1972. After his identification, Blassie’s family had him moved to Jefferson Barracks National Cemetery in St. Louis. Instead of adding another unknown soldier to the Vietnam War crypt, the crypt cover has been replaced with one bearing the inscription, “Honoring and Keeping Faith with America’s Missing Servicemen, 1958-1975.”


The Tomb was designed by architect Lorimer Rich and sculptor Thomas Hudson Jones, but the actual carving was done by the Piccirilli Brothers. Even if you don’t know them, you know their work: The brothers carved the 19-foot statue of Abraham Lincoln for the Lincoln Memorial, the lions outside of the New York Public Library, the Maine Monument in Central Park, the DuPont Circle Fountain in D.C., and much more.


Tomb Guards come from the 3rd U.S. Infantry Regiment "The Old Guard". Serving the U.S. since 1784, the Old Guard is the oldest active infantry unit in the military. They keep watch over the memorial every minute of every day, including when the cemetery is closed and in inclement weather.


Members of the Old Guard must apply for the position. If chosen, the applicant goes through an intense training period, in which they must pass tests on weapons, ceremonial steps, cadence, military bearing, uniform preparation, and orders. Although military members are known for their neat uniforms, it’s said that the Tomb Guards have the highest standards of them all. A knowledge test quizzes applicants on their memorization—including punctuation—of 35 pages on the history of the Tomb. Once they’re selected, Guards “walk the mat” in front of the Tomb for anywhere from 30 minutes to two hours, depending on the time of year and time of day. They work in 24-hour shifts, however, and when they aren’t walking the mat, they’re in the living quarters beneath it. This gives the sentinels time to complete training and prepare their uniforms, which can take up to eight hours.


The Tomb Guard badge is the least awarded badge in the Army, and the second least awarded badge in the overall military. (The first is the astronaut badge.) Tomb Guards are held to the highest standards of behavior, and can have their badge taken away for any action on or off duty that could bring disrespect to the Tomb. And that’s for the entire lifetime of the Tomb Guard, even well after his or her guarding duty is over. For the record, it seems that Tomb Guards are rarely female—only three women have held the post.


Everything the guards do is a series of 21, which alludes to the 21-gun salute. According to

The Sentinel does not execute an about face, rather they stop on the 21st step, then turn and face the Tomb for 21 seconds. They then turn to face back down the mat, change the weapon to the outside shoulder, mentally count off 21 seconds, then step off for another 21 step walk down the mat. They face the Tomb at each end of the 21 step walk for 21 seconds. The Sentinel then repeats this over and over until the Guard Change ceremony begins.
