A very simple adaptation to the card game of the same name.

Supplies: people, beer, and cards.
 

Deal the game as you normally would. Anytime you ask for a card and are

told to "go fish," you drink once.

Every time you have to give a card to another player, you drink twice, three times for face cards and aces.

Every time time you lay down a pair, your opponent(s) drink twice. It's that simple.
