There's a drunk walking down the street...

...and he walks up to a policeman and says "somebody stole my car!". The policeman asks where it was, to which the drunk replied that it was right on the end of the quay. The policeman tells him to go down to the station and report the theft.

As the drunk starts to walk off, the policeman says "before you go downtown, you'd better zip up your fly". The drunk looks down and says "oh man they got my girl, too".
