The crawl for this episode lists the cast of The Bloodhound Gang's "Case of the One-Ton Jewel," scheduled for Noisy/Quiet: Production & Processing of Sound (the premiere) but withdrawn due to time constraints. The cast of "The Case of the Educated Pig," which does appear in Episode 1, is not credited.
How fatal an error was that? In spiking Episode 44 (Near/Far: Space Travel) early in 1986 and prohibiting the episode called Food/Fuel: Fueling Machines after July 1987, CTW had no surviving crawl to list the "Educated Pig" cast. That is why this age-old Bloodhound Gang episode was reinstated in Your Body: Twins, in October 1988.
