Happy Birthday to Me! ... and him... and her...

Original image

I was talking to a friend of mine recently who makes his living as an actuary. We were talking about birthdays and I asked him why it seems like every time I go out to dinner on my birthday, there's at least one other person there celebrating his or her birthday, too, effectively stealing my thunder.

My actuary friend explained that if you got 23 people together in a room, there's a 50-50 chance of at least one coincidental birthday.

Seeing as restaurants usually seat at least twice that number (well, not the hoity toity establishments some of you might frequent, but, for those of us still throwing their birthday parties at T.G.I.F.s"¦), the odds get even better.

After the jump, you'll find a complete breakdown for those who are curious to see the math involved.

To figure out the exact probability of finding two people with the same birthday in a given group, it turns out to be easier to ask the opposite question: what is the probability that NO two will share a birthday, i.e., that they will all have different birthdays? With just two people, the probability that they have different birthdays is 364/365, or about .997. If a third person joins them, the probability that this new person has a different birthday from those two (i.e., the probability that all three will have different birthdays) is (364/365) x (363/365), about .992. With a fourth person, the probability that all four have different birthdays is (364/365) x (363/365) x (362/365), which comes out at around .983. And so on. The answers to these multiplications get steadily smaller. When a twenty-third person enters the room, the final fraction that you multiply by is 343/365, and the answer you get drops below .5 for the first time, being approximately .493. This is the probability that all 23 people have a different birthday. So, the probability that at least two people share a birthday is 1 - .493 = .507, just greater than 1/2.

Let Alexa Help You Brine a Turkey This Thanksgiving

There’s a reason most of us only cook turkey once a year: The bird is notoriously easy to overcook. You could rely on gravy and cranberry sauce to salvage your dried-out turkey this Thanksgiving, or you could follow cooking advice from the experts.

Brining a turkey is the best way to guarantee it retains its moisture after hours in the oven. The process is also time-consuming, so do yourself a favor this year and let Alexa be your sous chef.

“Morton Brine Time” is a new skill from the cloud-based home assistant. If you own an Amazon Echo you can download it for free by going online or by asking Alexa to enable it. Once it’s set up, start asking Alexa for brining tips and step-by-step recipes customized to the size of your turkey. Two recipes were developed by Richard Blais, the celebrity chef and restaurateur best known for his Top Chef win and Food Network appearances.

Whether you go for a wet brine (soaking your turkey in water, salt, sugar, and spices) or a dry one (just salt and spices), the process isn’t as intimidating as it sounds. And the knowledge that your bird will come out succulent and juicy will definitely take some stress out of the holiday.

Big Questions
Why Do the Lions and Cowboys Always Play on Thanksgiving?

Because it's tradition! But how did this tradition begin?

Every year since 1934, the Detroit Lions have taken the field for a Thanksgiving game, no matter how bad their record has been. It all goes back to when the Lions were still a fairly young franchise. The team started in 1929 in Portsmouth, Ohio, as the Spartans. Portsmouth, while surely a lovely town, wasn't quite big enough to support a pro team in the young NFL. Detroit radio station owner George A. Richards bought the Spartans and moved the team to Detroit in 1934.

Although Richards's new squad was a solid team, they were playing second fiddle in Detroit to the Hank Greenberg-led Tigers, who had gone 101-53 to win the 1934 American League Pennant. In the early weeks of the 1934 season, the biggest crowd the Lions could draw for a game was a relatively paltry 15,000. Desperate for a marketing trick to get Detroit excited about its fledgling football franchise, Richards hit on the idea of playing a game on Thanksgiving. Since Richards's WJR was one of the bigger radio stations in the country, he had considerable clout with his network and convinced NBC to broadcast a Thanksgiving game on 94 stations nationwide.

The move worked brilliantly. The undefeated Chicago Bears rolled into town as defending NFL champions, and since the Lions had only one loss, the winner of the first Thanksgiving game would take the NFL's Western Division. The Lions not only sold out their 26,000-seat stadium, they also had to turn fans away at the gate. Even though the juggernaut Bears won that game, the tradition took hold, and the Lions have been playing on Thanksgiving ever since.

This year, the Lions host the Minnesota Vikings.

HOW 'BOUT THEM COWBOYS?

The Cowboys, too, jumped on the opportunity to play on Thanksgiving as an extra little bump for their popularity. When the chance to take the field on Thanksgiving arose in 1966, it might not have been a huge benefit for the Cowboys. Sure, the Lions had filled their stadium for their Thanksgiving games, but that was no assurance that Texans would warm to holiday football so quickly.

Cowboys general manager Tex Schramm, though, was something of a marketing genius; among his other achievements was the creation of the Dallas Cowboys Cheerleaders.

Schramm saw the Thanksgiving Day game as a great way to get the team some national publicity even as it struggled under young head coach Tom Landry. Schramm signed the Cowboys up for the game even though the NFL was worried that the fans might just not show up—the league guaranteed the team a certain gate revenue in case nobody bought tickets. But the fans showed up in droves, and the team broke its attendance record as 80,259 crammed into the Cotton Bowl. The Cowboys beat the Cleveland Browns 26-14 that day, and a second Thanksgiving pigskin tradition caught hold. Since 1966, the Cowboys have missed having Thanksgiving games only twice.

Dallas will take on the Los Angeles Chargers on Thursday.

WHAT'S WITH THE NIGHT GAME?

In 2006, because 6-plus hours of holiday football was not sufficient, the NFL added a third game to the Thanksgiving lineup. This game is not assigned to a specific franchise—this year, the Washington Redskins will welcome the New York Giants.
