The man leaps up, runs out and jumps on his horse just as he thinks "Hey, I don't have a house."
He goes back in and sits down, and raises the glass to his lips again. Just then a man comes running up to the door and yells, "Hey Joe! Your dad has died!"
So he leaps up, runs out, gets on his horse and starts to head down the street when he thinks, "Wait a minute ... my dad died years ago."
He goes back to the bar, and sure enough, he's just about to take a sip of his whiskey when another guys runs up. "Joe! Congratulations! You've won the lottery! There's a pile of money waiting for you down at the post office!"
The cowboy gets up, leaps on the horse, and starts flying towards the post office. He almost gets there when he thinks, "Hey, wait a minute. My name ain't Joe..."
