A man is in bed with his wife when there is a rat-a-tat-tat on the
 door.
 
 He rolls over and looks at his clock, and it's half past three in
 the morning. "I'm not getting out of bed at this time," he thinks,
 and rolls 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 there is man standing at the
 door. It didn't take the homeowner long to realise the man was
 drunk.
 
 "Hi there," slurs the stranger, "Can you give me a push??"
 
 "No,get lost, it's half past three. I was in bed." says the man
 and slams the door. He goes back up to bed and tells his wife what
 happened and she says, "Dave, that wasn't very nice of you.
 Remember that night we broke down in the pouring rain on the way
 to pick the kids up from the baby-sitter 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 get lost??"
 
 "But the guy was drunk." says the husband. "It doesn't matter,"
 says the wife. "He needs our help and it would be the Christian
 thing to help him."
 
 So the husband 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, do you still want a push??" and
 he hears a voice cry out "Yeah please."
 
 So, still being unable to see the stranger he shouts: "Where are
 you?" And the stranger replies: "I'm over here, on your swing."
