A man called sarge is one of those movies that isn't for everyone, but those of us that don't hate it, love it. It is full of stupid jokes, as noted before in the vein of the naked gun and Airplane. Being set in WW2, it completely lacks any PCisms at all. Germans are "Huns" (or "krauts", Americans are "Yanks", English are "Limeys", french are "Frogs"... you get the picture.
Most of the jokes are crude and cruel, and that is why many of us love it so much. It had some very South-park like jokes years before there was a south park. And it has a great sense of self-awareness that is funny only if it is done correctly, which it is.
In the movie, Sarge and his platoon are supposed to blow up the fuel dump at Tobruk, in Norther Africa. i was surprised to learn that there WAS a fuel dump at Tobruk, and it's destruction had a huge impact on the tank war in norther Africa.
However, in the movie, sarge and his men are supposed to blow it up. They then find out (after the fact) that they Aren't supposed to blow it up. make sense? not really, but with parts like the one where Sarge calls the attention of an entire German regiment to point at one of his men and say "Hey Fellas, i got a Jew up here!!", it's pretty easy to forget the "plot" and just laugh at the NPC jokes.
Recommended for those with thicks skins, who love stupid humor. Helps if you have seen Patton and like old WW2 movies.
