|An incredibly simple game, with not a lick of skill required. My buddy Dave Wood and I came up with this circa 1984.
Get a group of people (5 or greater is best) situated together sitting on the floor, around a table, whatever. Each person has a quarter and a beer. The signal is given (come up with one on your own - it really doesn't matter), and everyone flips their coin. Majority wins, minority takes a hearty sip (e.g. 3 heads, 4 tails, and heads drinks). This action is repeated for as long as the participants can hold out.
If the coins all come up the same, everyone chugs their beer. If there are an even number of players, and there is a tie, then tails drinks. If someone fumbles their coin (or it hits the floor in the case of playing around a table), it's a stupidity chug. A need to go to the bathroom requires 2/3 approval from the rest of the participants and a chug.
