Remember shows like "Rocko's Modern Life" and "Ren and Stimpy" that were suppose to be for kids but turned out to be some of the most controversial cartoons ever?
Cracked.com should give you some articles on them.
I mean seriously, one of the characters does phone sex, in other episodes it is filled with -blam!-[-blam!-] references, lots of violence and sometimes blood, testicle references, etc.

My first thought was, [i]"I don't think this is going to go where you want it to go."[/i] Either way, didn't Looney Tunes get pretty controversial in some episodes during WWII?
