Some guys find a man lying on the sidewalk. They assume that the old guy is drunk, so they decide to be good Samaritans and get him home. They pick him up off the sidewalk, and drag him out the door. On the way to the car, he falls down three times.
He tells them where he lives and when they arrive at his house, they help him out of the car and he falls down four more times. They ring the bell, and one of the guys says to the woman who answers, "Here's your husband!"
The man's wife says, "Well, where in the world is his wheelchair?"
