The Cursing Clone

A mad scientist was feeling kind of lonely in his laboratory, so he decided to create a clone of himself to keep him company. His creation was mostly a success, but the clone had a very foul mouth, and it greatly disturbed the mad creator.
One day they went into town to get groceries at the store. Upon entering the store the clone let out a slew of epithets and profanities that would make a sailor wince. The embarrassed scientist spun around and forcefully shoved the clone out the door where he tumbled into the street.
A passing police officer saw this and immediately arrested the mad scientist.
The charge?
Making an obscene clone fall.
