Featuring the World Trade Center prominently, this episode was pulled after the 9/11 attacks. While not offensive on release, real-world events changed its context. It remained absent for years before reappearing.

Another odd inclusion for a kids’ show, this episode showed characters getting drunk and dying. Parents were furious, and it was never re-aired. The segment was meant as a warning but came off as too dark.

The original pilot featured a darker, more adult tone and strange characters. It aired once late at night and was never shown again. CBS shelved it in favor of a lighter remake.

Banned for depicting a Japanese-American as a traitor in WWII. CBS pulled it after complaints and never aired it again until the 2000s.

Though a U.S. classic, the BBC pulled it due to its thinly veiled masturbation theme. It aired once late at night, then vanished from the British lineup. American audiences embraced its boldness, but UK censors weren’t amused.
