How to play:

​

Everyone must drink with their left hand, except left-handed people who must use their right hand.

If you see someone drinking with the wrong hand, shout "Buffalo! Buffalo! Buffalo!" and either bang on the table or clap your hands. Once you start, everyone else should do the same. The person drinking with the wrong hand must finish their drink while everyone is shouting and clapping, and they cannot stop until their glass is empty.
