Strangers in the night.

A married couple were in bed one night when there was a knock on the door. The man went downstairs to find a man wanting a push. He said forget it and went to bed. When he went back upstairs his wife asked who was at the door. He told her some guy wanting a push and he went back to bed. His wife said, do you mean you didn't give him a push? After all the help strangers have given you over the years? How could you be so callous? You should be ashamed of yourself. Well he realized if he didn't get up and help the guy that he'd never hear the end of it. He went back downstairs and opened the door. It was pitch black outside and he couldn't see a thing. He called out, hey do you still need a push? A voice from the distance answered yes, yes I do. He asked where are you? I'm over here. Well, where's over here??? I'm on the swing.
