So, the South Park movie shot for a G-rating, and despite the film's title, some NC-17 footage was reluctantly deleted by Parker and Stone.
The Beavis & Butt-head movie was kept relatively tame, as if the producers were striving to avoid an R rating. Also, it's possible that they might have wanted to make sure the film could be shown on network TV eventually.
However, I can remember two early 1980's "family" films which seem to have had dirty words forced in for no other purpose other than to avoid a G rating.
Annie: Late into the film, Carol Burnett's character says "God dammit." It seemed so gratuitous that I suspected that her only purpose in saying that was to assure the film avoids a G rating.
Popeye: Also late in the film, Popeye is heard saying "Shit!" while jumping off of a ship. Since the scene is a long shot, the word shit could have very easilly been dubbed in as an afterthought.
I know I might be getting a bit off-topic (sorry), but can anyone confirm my suspicions that these two films were "toned up" to get PG ratings?
