Just for pure comic fun, The scene in 1941, (starring Dan Akyroyd and John Belushi, Joun Candy, Robert Stack and Ned Beatty)
when Slim Pickens, ( in the movie he is Hollis P Wood, a rural Christmas tree salesman) who is spotted and captured on the beach in California. The Japs had apparently lost their compass, and in a last ditch effort, they were gonna try and bomb Hollywood, which they seem to think is the "Heart" of America). is captured and the Japs try to make him talk. They strip him down, search him, and of all things, find a box of cracker jacks, the prize inside just happens to be a compass........the Japs are happy, until Pickens grabs and swallows it. Their only alternative is to "wAIT IT OUT" so they make him drink prune juice...hahaha..and hope it...."passes".....
If you are a Slim Pickens fan......( and who isn't)......yuo gotta love this scene...
