This Is My ...
A really simple game, but one that is also incredibly easy to mess up.
How to Play
Players sit in a circle and take it in turns to point to one of their body parts and say the incorrect name. For example, a player pointing to their eye might say "This is my chin". The next player continues in the same manner.
To make play more difficult, you can require that the next player makes their statement (e.g. by pointing to their ear and saying "This is my nose"), followed by the previous person's statement and action.
When someone messes up, laugh at them and tell them how stupid they are. They must drink half a beer.
