Separate into two teams, sitting on the floor ~10 feet from each other. Place a cup of water in front of each team. When it is your team's turn, one person will throw 5 bottlecaps trying to get them in the other team's cup, without the other team interfering. The other team drinks a half a beer for every cap that goes in, and 1 gulp for every cap that hits the cup but does not go in. Then someone on the other team throws 5 caps, then the next person on the 1st team goes, and so on.

Play to 5 goals, winning by 2.
