Paddy's been out drinking all night. The bartender finally shouts the bars closed. So Paddy stands up to leave and falls flat on his face. He tries to stand once more and falls flat on his face again.
Paddy figures he'll crawl outside and get some fresh air and maybe that will sober him up a little.
Once outside he stands up and falls flat on his face again. So he decides to crawl for a while then tries to stand up, again he falls flat on his face. Finally he ends up crawling all the way home, through the door and up to his bedroom.
When he reaches his bed he tries to stand again but falls right into his bed. As soon as his head hit the pillow he was well away.
The next morning he woke-up to his wife shouting at him. SO YOU'VE BEEN OUT DRINKING AGAIN!!. What makes you say that he say's with an innocent look on his face.
She said. The pub called. You've left your wheelchair there again.
