A cowboy walks into a bar and orders a whisky. When the bartender delivers the drink, the cowboy asks, "Where is everybody?"
The bartender replies, "They've gone to the hanging."
"Hanging? Who are they hanging?"
"Brown Paper Pete," the bartender replied.
"What kind of a name is that?" the cowboy asked.
"Well," says the bartender. "He wears a brown paper hat, brown paper shirt, brown paper trousers and brown paper shoes."
"How bizarre," said the cowboy. "What are they hanging him for?"
"Rustling," said the bartender.
