A man and his wife were awakened at 3:00 am by a loud pounding on the door.
The man gets up and goes to the door where a drunken stranger, standing in the pouring rain, is asking for a push.
“Not a chance,” says the husband, “it is 3:00 in the morning!”
He slams the door and returns to bed.
“Who was that?” asked his wife.
“Just some drunk guy asking for a push,” he answers.
“Did you help him?” she asks.
“No, I did not, it’s 3am in the morning and it’s well pouring with rain out there!”
“Well, you have a short memory,” says his wife. “Can’t you remember about three months ago when we broke down, and those two guys helped us? I think you should help him, and you should be ashamed of yourself!
