I'm not Drunk
2 or More
All the players get together in a room and make sure they all have a full glass or a fresh can for this game. Have more drinks available with easy access.
All players start by pulling one leg behind themselves and balancing on one foot. With the other hand they must drink every 30 seconds. (This is a lot easier if there is a timer) If you fall over or you give up you are out and you must take a shot.
If you are the last one standing in this position you win. You get to nominate someone to take a shot. This game gets more and more difficult as the game goes on.
