"This episode was considered disturbing enough for Conrad Bain to present a parental warning at the beginning. Even the narrator who catches us up on the action from Part One of this two-parter sounds kinda creepy, setting the appropriately dark tone for Gordon Jump (loveable, bumbling “Big Guy” Mr. Carlson from WKRP in Cincinnati) to portray a bicycle store-owning pedophile. Mr. Horton lures young boys to his store with free accessories for their rides as well as free pizza, ice cream and … wine. (Cue the ominous music.) Arnold and his friend Dudley fall prey to his tactics and soon they’re shirtless, playing Tarzan, and posing for Polaroids."
