A guy went to a psychiatrist because he was having severe problems
with his sex life. The psychiatrist asked him a lot of questions, but he
couldn't get a clear picture of the problems. Finally he asked, "Do you
ever watch your girlfriend's face while you're having sex?"
"Well, yes, I did once."
"And how did she look?"
"Oh boy, she looked very angry!"
At this point the psychiatrist felt that he was really getting
somewhere. "Well that's very interesting, we must look into this further.
Now tell me, you say that you have only seen your girlfriend's face once
during sex. That seems somewhat unusual. How did it occur that you
saw her face that time?"
"She was watching us through the window."
You don't stop laughing because you grow old, you grow old because you stopped laughing.
