I think its about time we had a few entries for drinking games...

Game1 (can't remember what its called... Any one know its name)
Game for 2 players.
Requirements
2 pints

Two people sit facing each other with both fists on the table. Each player takes turns naming the sum of the fingers that will be displayed after a count of three (Usually done by rapping with both fists three times and then the player whose turn it is naming the value saying what it will be. This must be done simultaneously as showing the value on your hands directly after the three).
The player can name either 0,5,10,15 or 20.
The sum is the sum of the hands of both players, for example after the count player one may be showing 0 on left hand and 5 on the right. Player two may be showing 5 on left hand and 5 on right making a grand total of 15.

Winning
The game may be played in either of two ways, if you both WANT to get drunk then the player who calls the sum right gets to drink three fingers. Alternatively if you don't the the player who gets the sum wrong twice in a row (i.e. the get the guess wrong on the first guess, then get another guess because they got it wrond) has to drink the 3 fingers.
The person who finishes there drink first has to get the next round in, depending upon which way round you're playing the winning rule.

Game 3:
As many players as you like
Each player needs: 1 bottle of beer and 1 very yukky sock

Open the beer
Put the sock over the beer
Down the beer as fast as possible through the sock
The fastest person wins

If you like you can do this while standing on one leg
