A cowboy who lost his horse

A cowboy goes into a bar, has a beer, walks outside and finds his horse has been stolen. He walks back into the bar, and fires his gun through the ceiling. "WHICH ONE OF YOU MOTHERS STOLE MY HOSS?" he yells. No one answers. "ALL RIGHT, I'M GONNA HAVE ANOTHA BEER, AND IF MY HOSS AIN'T OUTSIDE BY THE TIME I FINISH, I'M GONNA DO WHAT I DUN IN TEXAS."
He gets another beer, walks outside, and his horse is back. So he gets on it and makes to ride out of town. The bartender wanders out of the bar and asks, "Say pardner, what happened in Texas?"
The cowboy turns to him and says, "I had to bloody walk home."
