Alternatively, here is a great drinking game called Fives (based on Spoof, but no coins required http://en.wikipedia.org/wiki/Spoof_(game)). Prob best for small groups.
You sit in a group, elbows on the table, fists in the air.
You take in in turns to go, clockwise.
When it is your go, you say a number that is a multiple of 5, from 0 to number of people x 10
As you say the number, everyone can either keep one or both of their fists closed, or spread their five fingers out (i.e each hand either counts as zero or five).
If the number you say is equal to the number of fingers shown, next time you use one hand not two. And then the next go, if you get it right again, you are out. Play continues until there is one person left, who then drinks the forfeit.
