There were two lovers who had known each other not very long, so they shared strong mutual feelings. Just like us, we met "only" ten years ago, and still feel strongly about each other. (Master and audience laugh.) One day they went dancing and stayed out very late, yet they were reluctant to part even after they got out of the car. They hugged each other over and over again, talking endlessly.

At this time, a young man happened to park his car near them. He got out of his car, went up to them, hesitated for a moment, and then returned to his car, where he stayed and looked at them again. After a short while, he came over again, hesitated, and then returned to his car. He repeated his action several times. At last he stood on the other side of the road and stared at the couple, apparently at a loss. He put his hands in his pockets, then behind his back, and then in his pockets again, all the time staring at the two lovers.
Finally, the male lover couldn't put up with it anymore. He ran up to the man and asked, "You have been staring at us for half an hour. What exactly do you want?" "Well, I was trying to enter my house, but you were standing in the way, and I couldn't get in!"
