This guy had been been at a bar all night drinking. The bartender
finally says that the bar is closed. So he stands up to leave and 
falls flat on his face. He figures he'll crawl outside and get 
some fresh air and maybe that will sober him up. Once outside he 
stands up and falls flat on his face. So he crawls home and at 
the door stands up and falls flat on his face. He crawls through 
the door and up the stairs. When he reaches his bed he tries one 
more time to stand up. This time he falls right into bed
and is sound asleep. He awakens the next morning to his wife 
standing over him shouting at him. "So, you've been out drinking 
again!!" "How did you know?" he asks. "The pub called, you left 
your wheelchair there again."
