Beer Pong

1 regulation sized, hand painted ping pong table
2 ping pong balls
2 cups with water to wash balls (note the filth in said cup)
20 red plastic cups, 10 for each end
4 college students
beers, too many to count

The best part is that the ping pong balls must be "washed" before allowed back in the game after a fall to the floor. Gross.
