Have Fun
Take one can of beer and put in the middle of the table.
Spread the cards in a circle around the can
the first person takes one card from the circle
the second person also takes one card from the circle
the person who has the lower of the 2 cards drinks the difference
then the first person puts their card on top of the can with a minimum of 2 corners off the edge
keep going around until the cards or gone
whoever knocks the fan off the can has to shotgun the can
