1) A keg at home and a keg at second base. You cannot pass second or score at home without drinking a full beer at the keg.
2) You cannot have more than one player on a base, so if another runner
is coming up behind you, you must drink quickly or both be tagged out
on the same base.
3) All players must have a beer in hand at all times, including while trying to catch a ball in play.
The drinking can be toned down depending of the occasion. Like
only having one keg at second base. People can double up on a base if
they want to....etc....
