A man and his wife are awakened at 3 in the morning by a loud pounding at the front door. The husband gets the door, and discovers a drunken stranger who's standing in the pouring rain, asking for a push.
"Not a chance!" says the husband. "It's 3 in the morning!" He slams the door, and returns to bed.
"Who was it?" asks the wife.
"Just some drunken stranger asking for a push." He answers.
"Did you help him?"
""No, I didn't! It's 3 in the morning, and storming out there!"
"Well, you've got a short memory," says the wife. "Don't you remember about three months ago, when we broke down on the freeway and those two guys helped us? I think you should help him!"
The man rolls his eyes, gets dressed, and goes out into the pouring rain. "Hello?!" He calls. "Are you still there?"
"Yes!" comes the drunk's voice.
""Do you still need a push?"
"Yes I do!"
The husband squints around, but doesn't see anyone. "Where are you?" he yells.
"I'm over here on the swing!"
