A man and his wife are awakened at 3 O'clock in the morning by a knock on the door. The man gets up and goes to the door where a stranger is asking for a push.
"Not a chance," says the husband, "It's 3 O'clock in the morning!" He closes the door and returns to bed.
"Who was it?" asks his wife.
"Just a stranger asking for a push," he answers.
"Did you help him?" she asks.
"No, I didn't -- it's 3 in the morning."
"Well, you've got a short memory," says the wife. "Can't you remember about 3 months ago, when we broke down on holiday and those 2 guys helped us? I think you should help him."
The man does as he is told and returns to the front door and calls out in 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 man replies.
