In the dismal fourth season, Carvelli, played by Charles Fleischer joined the sweathogs three seasons after appearing in the episode when Horshack fought against him in a boxing match. Did anyone think that Carvelli add anything to the show in the absence of Gabe Kaplan and John Travolta? I thought he added little to the show, even after Beau, played by Stephen Shortridge was added to the cast.
