The film was censored by the studio prior to release. The affected sections are:
The word "motherfuckers" was censored by having "mother" bleeped.
Myron's masturbation scene originally concluded with an old clip of Oliver Hardy being sprayed with a champagne bottle. This footage was replaced with something less offensive, if you call associating sex with violence and death less offensive.
A shot of Shirley Temple being sprayed with milk from a cow's udder was removed on Presidential orders (she was a US Ambassador at the time).
All of these cuts bar the last are restored in the director's version included on the Region 1 DVD release of the film. The Region 4 has the censored theatrical cut.
