The Tale of Three Men

There were these three men; their names were Shit, Shut up, and Manners. One day, they were riding in their car, and Shit fell out, so Manners went out to pick Shit up, and Shut up went to the police station.

When he got there, the police officer said, "What's your name, son?" and Shut up said, "Shut up." The officer replies with, "Ummm...excuse me?!" and Shut up said, "Shut up!" and the officer said, "Boy, where are your manners?" and Shut up said, "Round the corner picking up Shit!"
