“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 it’s pouring out!”
“Well, you’ve got a short memory” says his wife. “Can’t you remember about three months ago when we broke down on holiday and those two guys helped us? I think you should help him.”
The man does as he is told and gets dressed and 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.
Harm.
