From a time (prior to the 1990s when political correctness ruined comedy) when comedy was funny. The classic military meme of confusion, incompetence, and slackery is dressed up by the not inconsiderable comedy and acting skills of Dean Martin and Jerry Lewis. My wife was in the Navy and swears that life really was like this, but also argues that, contrary to the song in this film, that she must have missed Naval Caviar Day.
Dean Martin's singing and straight-guy persona paired with Jerry Lewis' slapstick was a formidable combination. Sadly, most people who discuss this pairing act as if Lewis was *the* talent, to the exculsion of Martin. While nobody would deny that Lewis was an incredible talent, Martin's performances on his infamous Roasts and his comedy with the Rat Pack demonstrate that his straight-man comedy chops were not insignificant.
