Yeaa, we had to do the "birthday problem" in stats over last semester. Our teacher gave us the opportunity to try and figure it out beforehand, and everyone was very wrong. Very interesting.

Thanks for the link guys.
I don't think I've ever come across it before or if I have I didn't know it was irrational like pi.
