Bizz/Buzz. At the start of the game you decide on 2 numbers and multiples of those numbers. For example, let's say you selected 4 and 5. The players count off in succession but on the multiples you have to say bizz or buzz. It would go 1,2,3,bizz,buzz,6,7,bizz,9,buzz,11,bizz,13,14,buzz,bizz,17,18,19,buzz,21,22,23,bizz,buzz,26,27,bizz,29,bizzbuzz,31,bizz etc etc. When ever someone screws up they have to drink. If you want to make it more complicated you could reverse the direction of the count on a bizz or a buzz. Have fun.
