When I first learned this I got a bit confused when I realized that the product of primes (plus one) isn't necessarily prime.
This might make the proof simpler:
Multiply all primes
add one, then find prime factors
they aren't in the list
I wonder if anyone has a Pythagoras proof in a Haiku form?

This is really awesome. If nothing else, it makes a birthday gift entirely filled with random. So let's do this. The eBay APIs are pretty easy to use, so I threw together a little Flex app that searches for things under a dollar. Flex might not be the best platform for this, but at least it's reason...
