This guys in bed with his wife when there's a rat-a-tat-tat on the door. He rolls over and looks at his clock, and it's half three in the morning. He thinks about getting the door for a moment and rolls back over.
Then, a louder knock follows.
"Aren't you going to answer that?" says his wife.
So he drags himself out of bed, and goes downstairs. He opens the door and this guy is standing outside.
"Hey," says the stranger, "can you give us a push?"
"No, go to hell! It's half past three. I was in bed sound asleep," says the man and shuts the door.
He goes back up to bed and tells his wife what happened and she says, "Russel, you are such an idiot! Remember that night we broke down in the pouring rain on the way to pick the kids up from the babysitter and you had to knock on that man's house to get us started again? What would have happened if he'd told us to go to hell? You should be ashamed!"
So after that tongue-lashing, he gets out of bed again, gets dressed, and goes downstairs. He opens the door and not being able to see the stranger anywhere he shouts, "Hey fella, do you still want a push?" and he hears a voice cry out, "Yeah please, man."
So, still being unable to see the stranger he shouts, "Where are you?"
The guy replies, "I'm over here...on the swings!"
