Kickin' It 4x15

A documentary crew comes to film the dojo for a day, and Rudy takes advantage to make himself look good. Jack, angry that Rudy won't give him the sensei test, retaliates by convincing Rudy's grandmaster to fake being a fraud, demoting Rudy back to white belt. But Jack discovers that running the dojo is hard work. Meanwhile, after Jerry pranks him one time too many, Milton goes too far with pranks, not only on Jerry, but on the camera crew as well.
