A reporter makes a bet with the quarterback of the Tennessee football team as to how many digits of Pi he can rattle off. He wins.
Two guys offer a demonstration. This is amusing because they start off with that slightly-macho, jaded humor thing common nowadays...and then they start giggling when the pies come into play.
This woman coupled Pi Day with an pieing challenge for ALS, like last year's Ice Bucket craze. (By the way, ignore her advice on goggles and shower caps. Go big or go home! Don't be a muggle! You're not going to look any more dignified if you try dressing up like a deep-sea diver for your pieing. In fact, the Pie Gods will mock you forevermore if you do such a thing!)
Another challenge-type video here. This woman actually made this video last year, but she retweeted it yesterday for Pi Day, which is how I saw it. She is raising awareness for Huntington's Disease, and what I like about this (besides the pie) is that she uses clips from an episode of the best medical teevee show ever, Scrubs, to describe the disease and its effects.
This fellow invented a mechanical device for pie-throwing. Some logistics need to be worked out, obviously, but the idea is intriguing.
Actually, I'm not sure this has anything to do with Pi Day or not, but it got posted yesterday, so here's Suzanne Somers getting pied by her Dancing with the Stars dance partner.
Long live Pi, and pie!
