An Irishman is keen on a drink or three and he has been in the pub getting very drunk all evening.
He realises he will have trouble getting home but decides some fresh air could help him. He can't stand up but crawls out of the pub for some beautiful Irish air.
It doesn't help. He can't get up and he realises he will have to crawl home.
Some time later he gets to his home and manages to crawl upstairs and into bed without disturbing his wife.
The next day his wife asks him why he has got drunk again.
'But I was as sober as they day I was born!' He cried.
'Oh yes? Then why did that Pub ring me to say you had left your wheelchair behind last night?'
