Weekend Genius Challenge #5: More of Four


NOTE: This weekend challenge has been completed. If you'd like to guess the clues just for fun, go ahead, then see here for the answers and the name of this weekend's winner. 

This week, you'll have to decipher some clues to win a T-shirt... more specifically, they're words, phrases or names that contain only four unique letters. Each of the answers to the clues below is at least eight letters long, but each answer contains only four unique letters. An example? The song title "Remember Me" is nine letters long, but only contains four different letters (B, E, R, M). Ready? Here we go:

1. Cindy Brady's one?
2. Cindy & Bobby's record?
3. Like The Commodores?
4. Like a "wife-beater"?
5. Stupidity?
6. Slum building?
7. "The Big Cat"?
8. Mighty river?
9. Kayser-Roth brand?
10. Costs 50 cents, usually?
11. Armed ________?
12. Often fooled by white paint?
13. Cars' last?
14. O.J. non-book
15. Tobasco veggie?

When you've figured them all out (or think you have), leave a comment to this post with your 15 numbered answers. You only get one shot, so be careful. The first with all correct (or the one with the most correct by Monday) will win a T-shirt!


  • One entry per player.
  • At the end of your post, list which T-shirt you want from the store (you can browse all of our punny shirts by clicking this link).
  • Comments are moderated, so they won't show up until we release them. The correct answers (and the winner's name) will be revealed first thing Monday morning.
  • Due to the "esoteric" nature of this puzzle, your answers must match ours to win the prize, even if you have an alternate answer you think is valid. That said, if you've got a really hilarious and plausible answer that doesn't match ours, you just might get a shirt out of that too.

Good luck!

Gasp... Is This the End of the Weekend Genius Challenge?

It's been a struggle to come up with mental exercises that are difficult enough for the many, many brilliant folks who read mental_floss and visit mentalfloss.com. It's difficult to develop puzzles that are (1) safe from Web searches, but (2) not impossible to solve. After seeing many difficult contests won in a matter of minutes, I'm taking this weekend off to reassess the Weekend Genius Challenge.

We get the most entries in creative-type challenges... having you write haikus using the two words from the ReCaptcha service, asking you to tell us where the "lost" hour went during Daylight Saving Time, and so forth. So we're considering going that route for future WGCs. What do you think? Ideas, suggestions, and comments are more than welcome. In fact, if you'll kindly take the time to chime in, we'll pick a random comment and send the responsible party the mental_floss T-shirt of his or her choice. Thanks in advance.

In the meantime, we'll continue to do Brain Games on a daily basis, with puzzles of varying description each weekday. And we'll have results for the last two WGCs in a day or two. Have a great weekend, everyone!

Weekend Genius Challenge #30: Unwritten Rules

We got SO many entries for last week's WGC that it may take us the rest of the weekend to sort through all the responses... but we'll choose a winner before Monday arrives. In the meantime, since you all seem to enjoy being creative, let's give away another T-shirt by unleashing Weekend Genius Challenge #30!

Many "unwritten rules" guide our planet. Here are a few I've jotted down over the years:

1. All really good architects must go by three names.

2. The number of leaves that end up in your yard in the fall has more to do with your neighbor's trees than your own.

3. During trip to a restaurant with someone else, when you ask for two orders of fries, both orders will be incredibly large and too much to eat. But the next time you go to that restaurant with someone else and ask for only a single order of fries -- thinking it will be enough to share -- the order will be incredibly small.

Your job is to fill us in on the "unwritten rules" that you've experienced in life. The mind behind the one we vote best will win a T-shirt of his or her choice from our online store. REALLY, REALLY IMPORTANT: To be absolutely clear, your entries should have nothing to do with identity, race, color, religion, sexual preference, political preference, physical or mental issues, or anything bordering that. In other words, don't direct them towards any person or group of people who might possibly take offense. So be smart. Play nice. Sit up straight. And tell your sister you love her.

Also, please remember that all comments will be moderated before they're released, so it may take a while for them to appear on the site. Enter as many times as you like, but please put each entry in a separate comment. Good luck!
