A guy spends the night drinking in a bar.
When he finally leaves at 4:30, he immediately falls over. He crawls for a while, then tries to get back up, falls, crawls, gets back up.
On an on he goes on doing this until he finally gets home. There he falls in his bed and promptly starts snoring.
In the morning, his wife sighs, 'you’ve been drinking again, Joe, haven't you?'
‘How on Earth could you guess that, darling?'
'You went and left the wheelchair at the bar again!!!'
