What You Need:

2 ping pong balls
2 teams of 2 people
20 plastic cups
a big table
a shit load of beer

How To Play:

Put 10 cups in triangular formation on each end of the table. Fill each cup with as much beer as you wish. Each partner gets a chance to throw a ball in a cup on the opposite side of the table. You must drink the cup   directly after the ball goes in, no waiting. You can bounce the ball but then other team can swat the ball. If a bounce goes in the other team must drink two cups, the cup the ball went in and a cup of your(the throwing teams) choice. Also, if the ball spins in a cup, bitches blow; girls can blow the ball out but if it touches the beer the shot counts. If the ball misses the table, take off an article of clothing. You can condense the cups at, and only at, 4 and 2. The fist team out of cups wins, but the opposing team gets a chance to rebut by having to make the ball in every cup that they have left in a row to win. If there is only one cup both partners have to make it into the one cup. The losing team has to drink their left over cups. This game is great fun and you should be drunk in 2 or 3 games.
