Alcohol power

An Irishman's been at the pub all night drinking. The bartender finally says that the bar is closed. So the guy 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 all the way home and at the door stands up and again 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 manages to pull himself upright but he quickly falls right into bed and is sound asleep as soon as his head hits the pillow.

He awakens the next morning to his wife standing over him shouting at him. "So, you've been out drinking again!!"

"And what makes you say that?", he asks as he puts on his best innocent face.

"The pub called. You left your wheelchair there again".
