Pi

Pete downloaded an app that displays a few thousand digits of Pi. Somehow he and Sam started memorizing Pi and that was the big thing for 3-4 days. They got up to about 40-50 digits at one point. The video below is just Pete reciting some digits in Pi, but there is something else about it (if you watch carefully) that actually makes it one of my favorite Pete/Sam videos ever.

In the interest of equal time, here is a video of Sam doing Pi:

Sam's video has fewer digits, but that's only because I recorded it a day earlier than the Pete video and they were learning about 10-12 extra digits per day.
