A man went into a bar and ordered several shots of vodka. By the time the bar was closing, he was wasted. He got up to leave and fell flat on his face. "Well, I don't want the bartender to think I'm drunk, so I'll pretend I tripped and I'll try it again."

So he gets up and falls on his face. "Well, the door's not too far away; I'll just crawl." When he gets outside he thinks, "Well, I only live 4 blocks away; I can make it that far." So he stands up and falls on his face. He decides he'll try it 1 block at a time, and at every block he falls flat on his face. Finally he makes it home, stands up and falls on the bed. In the morning his wife wakes him up. "You were drunk again last night, weren't you?" "How did you know?" "The bartender called. He said you left your wheelchair at the bar."
