I read this joke in an old issue of the Boys' Life magazine.... I might have it slightly wrong, but here goes....
A dog, a cat, and a mouse were playing cards. The cat got thrown out. Why?
Because he was a cheetah!
I was on a family camping trip, and there was a community campfire event where they invited people up to tell jokes. Little 8 year old me was the first one to volunteer, and I told that joke. More people began going up to tell jokes after that, so yay little past me!
