I watched the episode of Rocko's Modern Life where they go grocery shopping last week and noticed something rather naughty. At one point, Spunky gets attacked by a meat wrapping machine and put out for sale. A giant bull man grabs Spunky and Rocko attempts to change his mind by mentioning various chemicals the meat could contain, such as CFCs, MSG, and even PCP, at which point the bull says "I like PCP." and walks off with the meat.

Being twenty years old I realize how twisted that is in a kid's cartoon.
