5. "Let Jesus f**k you! Let Jesus f**k you!" - The Exorcist (1973)
Little Regan gets possessed by a demonic entity and starts behaving like a brat with really bad behaviour - cussing at adults, levitating, spewing forth gallons of pea soup, but her most startling moment comes with a humble crucifix. She grabs the crucifix and uses it effectively as a sex toy, ramming it into her vagina whilst screaming "Let Jesus f**k you! Let Jesus f**k you!". This scene is startling on a number of levels. One, some viewers may view the scene as being sacrilegious. Two, it's a young girl masturbating and three, it looks like what she is doing to herself is very painful. I can imagine audiences being very shocked and disgusted in the 1970s, and the scene still has the ability to shock people 40 years later.
