Superstone

When the actor who portrays TV’s “Superstone” walks off the job, Fred is recruited to fill in and play him, but he is framed by two thugs who knock him unconscious, dress in his costume (frequently muttering Superstone’s yell, “Beh-heh-hee-HAH-hah”), and steal the cash box. He and Barney are able to find the true thieves down on the docks, based upon the strong clue that one of them keeps repeating, “Yeah, yeah: I’m hip, I’m hip!”. The teaser is a preview from the middle of the episode.
