Comedian Howie Mandel took advantage of his appearance on the Tonight Show last night to plug his son's Sci-Fi Channel show by showing a clip of the young man taking a solid smack to the chops during a video prank. Between laughs, the proud father told host Jay Leno that he really enjoys sitting at home watching the video on repeat. Up next on Jimmy Kimmel Live, Jada Pinkett-Smith lets Jimmy know that there are a whole bunch of reasons why it's easy for her to get the new Karate Kid to do his chores, and Craig Ferguson reveals why he feels like his studio audience is faking it night after night on The Late Late Show. Wrapping things up on Late Night with Jimmy Fallon is Jason Bateman performing an impromptu version of the theme from his hit show that wasn't Little House on the Prairie.
