Party Ideas For Math Nerds?

Slashdot has some funny ideas (mixed amongst a lot of bitter comments):

The trick is to do things she and her friends like in unexpected and subtle ways. For example, arrange the appetizers in the Fibonacci series (or get really daring and stack them vertically using Pascal's triangle). Use geometry to decorate (especially Pi)

Don't forget drinking games: It's not that hard, you just pick a card and drink half the sum of the prime factors in fingers. If you get it wrong, you have to stand on your head and recite pi backwards (as hard as it sounds.)
