One thing "Hey Arnold!" Shoulden't have done
The epsidoe of "Hey Arnold" where dino spumoni faked it's death had something they shoulden't have done. It mentions already existing in reality bands from the early nineties Run DMC, Guns "N" Roses, and Tiffany. This is sort of like when Mtv banned Neil Young's "This Note's for You" with it's mentions's of Pepsi, and Coke, and Calvin Klein commercials. This is a cartoon show you can't mention real life bands or singing artist in a cartoon you have think of one.
