"S-Out" - Bottom
For those who don't know, Bottom is a British show that involves two pranksters with no jobs or money running around in Hammersmith, West London. The show was meant to be crude, but one episode was completely condemned for crossing the line. In "S-Out," the two characters spend the night on Wimbledon Common. This wouldn't have been odd except for the fact that the real-life murder happened in that same area. Fans thought that they crossed a line by shooting there.
"See Me, Feel Me, Gnome" - The Powerpuff Girls
The Powerpuff Girls is filled with innuendos meant for adults that go over kids' heads (a lot of kids' cartoons are like that!). But one episode was a bit too much for most people and ended up getting banned. The episode "See Me, Feel Me, Gnome" was apparently too close to the themes of communism. So, the episode was shot.
