Wooden Leg

Listen up, buttercup. This joke ain't rocket science. It's playing on stereotypes, see? An Indian with a wooden leg is called "shit on a stick," which is already offensive, I know. And then, if he's got two wooden legs, he's a "waste of lumber." Get it? Lumber, like wood for the legs? It's not funny because it's clever, it's 'funny' because it's ridiculously offensive and plays into negative stereotypes. You wouldn't get it though, cause you breathe through your mouth, lol.
