The Mathematical Pi Song (abridged version), without the word "masturbate" included!

The Pi Episode: Math Bites with Danica McKellar. This would be a great video to show on Pi Day. It is about 6 minutes long and entertaining and it also stars Winnie Cooper (I mean Danica McKellar). Make Middle School Math Pi Day an event at your school.

Great High School Math Poster on Pi . Okay, it's not funny, but it's 'Pi'.

Pi played on a piano - endless!
