On the way out to the car, the drunk falls over a few times, and crawls the rest of the way to the car. When they get to his house, he can't even walk, and falls five times on the way to his own front door. The good samaritan helps him the rest of the way, and rings the doorbell.
The drunk's wife opens the door. He says: "Sorry to wake you m'am. Your husband's had a few too many, so I drove him home for you." The wife gratefully responds: "Thank you, sir, that's very kind of you....where's his wheelchair?"
