Fill a pitcher up as much as you want with beer and place it on one table and stand behind either another table or a kitchen 'island'. Bounce a ping-pong ball from the table or island and try to make it into the pitcher.
Every time you make it in the pitcher it is worth 2 points and the other team has to drink that amount. You can play to 12 or any other number you wish. Once that number as been reached the other team has a chance to save by taking one shot and making it. If they don't make it they drink the pitcher.
