Everyone here who watches 4Kids' One Piece dub has already noticed how censorship can look extremely funny. Now, let's talk about that for different series.
I thought I'd start off by naming the classics:
Dragonball Z (Old Ocean Group dub)
-Vegeta destroys a building and says "It must be empty because it's a Sunday". But, the whole city is crowded the next minute.
- Nappa destorys a plane Tien (With a shocked expression): I can see their parachutes, they're alright.
Zatch Bell
-Gun edits: All of them are changed to glowing green laser guns. At least it's better than the second episode where that bank robber had that purple meatball launcher.
Sailor Moon S
Uranus and Neptune are boy-crazy cousins.
