Clone

Once there was a mad scientist who worked by himself in his laboratory. He was so lonely that one day, he decided to clone himself. Everything worked perfectly, except that the clone had a very foul mouth. The scientist worked with the clone, but ,alas, he could not make the clone clean up his language. He got so tired of the clone's language that one day he pushed him off the end of a cliff. A policeman rushed up to him, and yelled

"You are under arrest! You are under arrest!"

"What for ?",the mad scientist asked.

And the answer was: For making an obscene clone fall.
