Drink bowling is good. Buy a 4 pint pitcher each(you will need more), then play a game of bowling, for every pin knocked down, you add a finger of drink to a glass. As soon as you see another play fill thier glass, you may shout 'Gutterball', 'Spare' or 'Strike'. Gutterballs allow the person to pour half of their drink onto another player. If gutterball is called the last player to exclaim 'Gutterball!' recieves the drink, at which point 'Spare' rules take place, and the reciever downs half their drink. Spares are half the pint downed. You may call spare at any time. Strikes are full pints downed. You may only call strike when the player strikes. If the player bowling scores a gutterball, spare or strike whilst bowling, they may either pass thier drink on, challenge someone else to spare, or to strike thier drinks. If a player can not complete downing a 'spare' or 'strike', they foul, which means next round they must attempt to 'spare' or 'strike' again, which continues until they succeed. It's not so bad as long as everyone is on the same drink.
