A man is in the pub, having a few drinks with his mates. At closing time the man goes to stand up, but falls straight down again onto the floor.
"I must have had more to drink than I thought!" thinks the man. He tries to stand up again, but keeps falling back down.
Eventually, the man crawls home, and falls asleep.
Next morning, his wife wakes him up with a cup of tea.
"Good night last night?" she asks
"Not bad" the man replies
"Did you have one too many with your mates?" she asks
"What makes you say that?" says the man
"Cause you left your wheelchair in the pub..."
