Angus has been at a pub all night drinking. The bartender
finally says that the baris 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 again. He crawls through the door and up the stairs.
When he reaches the 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."
