There is a man sitting in a pub and it's 2 AM. So he thinks: let's go home.
He stands up from his seat, but he drops on the ground immidiately. So he thinks: wait, let's first drink some water, so that I might walk again and my wife does'nt notice I'm drunk.
So he drinks a lot of water, he stands up and drops down again.
The man thinks: Well, let's crawl home then. So when he comes at home he gets in bed and his wife doesn't notice anything.
The next morning: the man wakes up and his wife stands beside the bed. She says: "So, you have been drunk last night, haven't you?". "Why that," asks the man. "Well, you left your wheelchair in the pub."
