Cowboy in El Paso

A cowboy is sitting in a saloon...

He looks out the window and notices his horse has been stolen. He turns around and shouts to the rest of the bar, "Alright, looks like one of you mangy dogs done stole my horse. Now, I'm going to go take a leak. And when I get back, my horse better be back outside... or else I'm going to have to do what I did back in El Paso... and I don't want to have to do what I did back in El Paso." So he gets up, heads off to the toilet, and when he returns, sure enough, his horse is tied up outside right where he had left it. As he is saddling up, some of the people from inside the bar come out and ask, "Hey, stranger. What was it you did in El Paso that you didn't want to do again?" "I walked home."
