The town sheriff walks into the bar. There's a dead silence as the sheriff surveys the crowd impressively. The bartender asks in a timid voice, "Can we help you, sheriff?"
"Any o' you boys seen Brown Paper Jack?" booms the sheriff. No response from the bar.
Finally, the bartender asks, "What's he look like, sheriff?"
"He's wearing a brown paper hat. He has a brown paper vest over a brown paper shirt. His pants and boots are made of brown paper and he carries his gun in a brown paper sack." Again, silence in the bar.
The bartender says, "And what's he wanted fer, sheriff?"
"The usual," says the sheriff. "Rustling."
