I love that movie too. My favorite character is Major Kong portrayed by Slim Pickens.
Survival kit contents check. In them you'll find: one forty-five caliber automatic; two boxes of ammunition; four days' concentrated emergency rations; one drug issue containing antibiotics, morphine, vitamin pills, pep pills, sleeping pills, tranquilizer pills; one miniature combination Russian phrase book and Bible; one hundred dollars in rubles; one hundred dollars in gold; nine packs of chewing gum; one issue of prophylactics; three lipsticks; three pair of nylon stockings. Shoot, a fella' could have a pretty good weekend in Vegas with all that stuff.
If you look closely at the Strangelove "survival kit" scene, you'll note that although Picken's says "...a pretty good weekend in Vegas" on the soundtrack, his actual words were "...a pretty good weekend in Dallas." The scene was shot before Kennedy was assasinated in Dallas. It was felt (rightly so, in my opinion) that Dallas would have not been a particulaly funny punchline under the circumstances, so the line was redubbed before release to the theaters.
That little phrase book/bible has to be the funniest thing ever, but the whole movie is a riot.
Look closely - Vegas was dubbed in. The original phrase was 'Dallas', however, the movie was released the year after JFK was assasinated, so they re-dubbed the city.
