Birthday nerdjoy

In looking online for a birthday eCard (happy b-day Rebecca!), I stumbled upon a Wikipedia page on the Birthday Paradox. Quite simply:
A graph showing the probability of at least two people sharing a birthday amongst a certain number of people.
In probability theory, the birthday paradox states that given a group of 23 (or more) randomly chosen people, the probability is more than 50% that at least two of them will have the same birthday. For 60 or more people, the probability is greater than 99%, although it cannot actually be 100% unless there are at least 366 people.

Sorry to nerd out, but that is so cool. I love the fact that it's 23 people (my favorite number). Get a group of 23 or more together and test this theory!
