A scientist finally succeeded in cloning himself, but all his clone
would do was sit around and spew out cuss words. After a week of
this, the scientist finally got fed up and pushed his clone out of the
10th-story office window.

A short time later there was a knock on his office door. The scientist
opened the door to find a policeman who said, "I'm going to have to
arrest you for making an obscene clone fall."
