It's Spring, Sergeant (1974)

The Polish comedy It's Spring, Sergeant (1974) tells the story of Sgt. Wladyslaw Lichniak (Józef Nowak), whose attempts to finally get a high-school diploma are put in serious jeopardy by the interference of his well-meaning neighbors. Along the way, we get a look at Malgorzata Pritulak’s ass-Krakow as some guy pounds on it with what looks like a frying pan. Mr. Skin can think of better things to pound that thing with!
