Cowboy without a horse

A cowboy rode into town and stopped at a saloon for a drink. Unfortunately, the locals always had a habit of picking on strangers, which he was. When he finished his drink, he found his horse had been stolen.

He goes back into the bar, handily flips his gun into the air, catches it above his head without even looking and fires a shot into the ceiling.

"WHICH ONE OF YOU SIDEWINDERS STOLE MY HORSE?" he yelled with surprising forcefulness. No one answered.

"ALL RIGHT, I'M GONNA HAVE ANOTHER BEER, AND IF MY HOSS AIN'T BACK OUTSIDE BY THE TIME I FINNISH, I'M GONNA DO WHAT I DUN IN TEXAS! AND I DON'T LIKE TO HAVE TO DO WHAT I DUN IN TEXAS!"

Some of the locals shifted restlessly. He had another beer, walked outside, and his horse is back! He saddles-up and starts to ride out of town. The bartender wanders out of the bar and asks, "Say partner, before you go...what happened in Texas?"

The cowboy turned back and said, "I had to walk home."
