ping pong table, set up 10 beers on either side like bowling pins (in a triangle). The object is to try and throw the ball into the other side's beers. If you get one in they have to drink it. You just take turns and go back and forth until there is no more beer. Some people have special rules regarding blowing the ball out when its toilet-bowling around the rim of the cup, some people allow re-racks halfway through the round, some people allow bounces while others require direct shots. There's room for customization of the rules (often depends on whether girls are playing)h:
