When I held my notorious/legendary "Jay Ward Film Festival" at UCLA in the early 80s (attended by Bill Scott, June Foray, and more!), Bill (the voice of Bullwinkle and so many more familiar voices) told a story of would-be "censorship" on "Rocky and His Friends" (1959-1964).
Seems that they had done a sequence where Rocky and Bullwinkle are in a pot being cooked by natives. The sponsor went nuts. "You can't have cannibalism on a kids' show!" the sponsor proclaimed.
The reply: "Is it really cannibalism to cook a moose and a squirrel?"
The bit stayed in.
I have an audio recording of the entire proceeding, including a live performance and amazingly prescient Q&A session. I really need to get it back online.
