Buzz and Fizz

Stolen from: A Network for Jewish Youth

Everybody sits or stands in a circle. Going clockwise, everybody takes it in turn to say a number, starting from one. When they get to a multiple of 5, they have to say "fizz" instead. When they get to a multiple of 7, they say "buzz" instead. If players make a mistake they're out.

To make it even more complicated, try changing direction whenever people say buzz or fizz. And if you manage to get to a number that's a multiple of both 5 and 7, shout "Shizzle!" and make everybody run round the room or something.
