mens pi hoodie from think geek
You will find no pie/pi references here, no matter how easy it would be for a pun-lover such as to be impaled upon the sword of lame writing (which, lets be frank, happens around here quite a lot), I shall resist!

The cool thing about this hoodie is that the pi symbol itself is actually made up of lots of tiny numbers, and apparently the numbers follow the sequence of pi, which in your head is a pretty logical thing to do if you were brainstorming pi related design ideas, but its still nice to see someone actually make it.
