Joanie Loves Chachi: The Complete Series—Seasons 1 & 2

Joanie Loves Chachi was a misbegotten spin-off from Happy Days that only lasted a mercifully brief 17 episodes. Ranked No. 17 by TV Guide on a list of TV's “25 Biggest Blunders,” this series jumped the shark in its opening credits, which featured a cringe-worthy duet by its appealing (albeit musically and comedically-challenged) stars, Erin Moran and Scott Baio. The series packed Richie Cunningham's sister and Fonzie's cousin off to Chicago to pursue their rock dreams. Providing adult supervision and comic relief were Chachi's mother (Ellen Travolta) and Happy Days regular Al Delvecchio (Al Molinaro), married owners of the restaurant where Joanie and Chachi performed. Joanie Loves Chachi was filmed before a live studio audience, which dutifully erupts whenever Chachi (and to a lesser extent, Joanie) enters the scene, laughing hysterically at the lame jokes. Happy Days icons Tom Bosley and Marion Ross, as Joanie's parents, and Henry Winkler's Fonzie were brought in for guest star appearances, but it wasn't enough to save the show, whose greatest (if also dubious) claim to fame may be a name-check in the comedy Dodgeball. Let's just leave it at that. Not recommended. (D. Liebenson)
