Because it is a children's cartoon show from the mid 1990s, Rocko's Modern Life had a virtual laundry list of "adult" jokes and innuendo that (for the most part) got by without the censors intervening. It can be said that this show did a better, subtler job of this art than its contemporary at the time (John Kricfalusi's The Ren and Stimpy Show), but, as always, Your Mileage May Vary.
