This has nothing to do with the US postal service.
There was a western made in 1942 called "Jackass Mail". Have the gang remake an X-rated version of the movie or redo some of the best 3 Stooges scenes, by using actual black and white film equpment from the early 1940's. Similiar to George Clooney's film "The Good German".
Watching Johnny's stunts, Pontius's penis, Steve-O's vomiting, and the rest of the gang on old school black and white film?? Absolutely Pricesless.
