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 went back into the bar, handily flipped his gun into the air,
 caught it above his head without even looking and fired a shot into
 the ceiling.  "WHICH ONE OF YOU SIDEWINDERS STOLE MY HOSS?" he yelled
 with surprising forcefulness.
    No one answered.
    "ALL RIGHT I'M GONNA HAVE ANOTHA BEER, AND IF MY HOSS AIN'T BACK
 OUTSIDE BY THE TIME I FINISH, 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
 saddled-up and started to ride out of town.
    The bartender wandered out of the bar and called to him, "Say
 partner, before you go... what did happen in Texas?"
    The cowboy turned back and said, "I had to walk home."
