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. Everytime you have to give a card to another player,
you drink twice, three times for face cards and aces. Everytime time you lay
down a pair, your opponent(s) drink twice.

It's that simple.
