Okay Frank, I'll explain.
2 Teams of 2 people each, 1 team per side of table
6 cups filled halfway up with beer on either side
2 Pingpong Balls
Each team takes turns shooting the ball into the other teams cups, 1 shot per player. If the ball goes into the cup, the cup is removed, and the other team has to drink it. If you bounce the ball off the table and into the cup, it counts as 2 cups that have to be taken away, but the other team can slap/grab the ball once it touches the table, so you have to be sneaky. If you sink all the other teams cups before they make one of yours, they have to run around the house/apartment complex naked.
