"Horshack vs. Carvelli" not only featured the second appearance of Charles Fleischer as Carvelli (introduced in "Sweatside Story"), but also the first appearance of regular Carvelli sidekick Wilbur Murray (Bob Harcum), and the only entry to be scripted by Garry Shandling, already a veteran of four episodes of SANFORD AND SON. All four Sweathogs want to challenge Carvelli in a boxing match, only for Horshack's taunts to put him in position to be kissing the canvas. The bets are on that Arnold doesn't survive the weigh-in. We get another mention of Bonzo Maretti (who ate his opponent!), but receive our only glimpse of Dino 'Crazy' Delaney (Mark Evanier), handcuffed to his probation officer!
