|Grab a deck of cards. To choose to see who goes first play high card. The person with the highest card of the group gets to either go first or he/she chooses who goes first.
Now everyone has played Memory when they were a child, well the setup is the same. Lay the deck spread out and faced down. Now the group of people sits down in a circle around the cards, and the person selected to go first simply plays memory.
If that person is successful he/she gets to select a person to drink a shot or a gulp of beer. If they get a matching pair of the same color (i.e. a 5 of spades and a 5 of clubs), then they get to have 2 people drink or 1 person drink twice. If the person is unsuccessful, then they have to drink a shot or a gulp of beer, and the person to their left goes.
So you see there will be a lot of drinking, especially in the later rounds of the game. If you're caught trying to cheat you have to drink three shots or down 2 beers, before the game resumes, and it's your turn. We all hate cheaters, but in this game we all secretly hope to catch someone.
I suggest to get more than 2 people to play, so there is more alcohol consumption, however a minimum of 2 people is required. Also, shots are prefered to beers because of the high alcohol content. Cheers!
