"Not a chance," says the husband - "It's three o'clock in the morning!" He slams the door and returns to bed.
"Who was it?" asks his wife.
"Just a drunken stranger asking for a push," he answers.
"Did you help him?" she asks.
"NO, I didn't - it's three in the morning and raining cats and dogs out there!"
"Well, you've got a short memory," says his wife. "Can't you remember about three months ago when we broke down on our vacation and those two guys helped us? I think you should help him."
The man does as he is told, gets dressed, goes out into the pounding rain and calls out into the dark, "Hello-are you still there?"
"Yes," comes the answer.
"Do you still want a push?" calls out the husband.
"Yes, please!" comes the reply from the dark.
"Where are you?" asks the husband.
"Over here on the swing," the drunk replies.
