Fuzzy Duck
Close but no cigar. We used the following rules:
Ace to 4 - Red means for yourself, black means to give out. E.G 2 of Spades means you dish out 2 fingers, 2 of hearts means you have to do the 2 fingers.
5 - Game of 5's
6 - First 3 6's have to put a bit of drink in a glass in the middle. The poor character who picks the 4th number 6 card has to add to that glass and finish it off.
7 - A game of 7's
8 - Anything from the list, e.g. create a new rule, choose to dish out 4 fingers, play a game of 5's or 7's etc.
9 - Thumbmaster (Someone puts a thumb down somewhere the rest of the group must match, popular target is crotch/boobs, last person gets fined)
10 - Topic card. The person picking the card has to choose a topic, e.g. football grounds/type of beer/pizza toppings. Everyone else in order has to name a football ground/type of beer/pizza topping but the same one can't be said twice. The one who can't think of something for that topic must drink up.
J - Shotgun master - Before the end of the game, the shotgun master must stand up and wave a shotgun (made of air) above the other players heads. The last person to duck must drink up!!.
Q - Question card! The person who picks this keeps the card til they ask another player a question. If the sender of the question gets told to do one and sod off then they have to drink. If the reciepent answers the question, they have to do the drink (2 fingers).
K - Everyone fills their glass up and starts drinking. However, you can't stop drinking until the person to your right has finished. Therefore the person to the left of the guy that picked the card stops when the card holder stops, the third stops when the 2nd stops etc. The poor chap to the right of the card holder normally doesn't fair to well.
All in all a bloody good game. Spend many nights at uni playing it and it usually ended up with some wacky story for the next day.
Another good one is Centurion

. All the players have a number of can's of larger lined up and a shot glass. There needs to be a visible clock with a second hand as well.
Fill the shot glasses up and take a shot every minute. It sounds easy but after 30-40 the minutes pass really quickly. Still sound easy? Make it too a hundred and keep going and THEN bear in mind your not aloud to leave the room for the loo!!

If you leave the room your game is over and clearly you don't win. I wouldn't recommend going playing this game before a night out as even though it's pretty quick, you really do get pretty hammered.
