7. The Greasy Strangler
There are the films of John Waters, there is the anti-comedy of Tim & Eric, there is the entire Transgressive art movement, and there is The Greasy Strangler, which blows kisses to shock cinema history as it careens off a cliff in a blazing fireball of WTF. Technically there's a plot: After a string of lubricated murderers, Big Brayden sets out to pin his dad, Big Ronnie, as the killer. But there's nothing straightforward about Greasy Strangler, which piles on exaggerated nudity, demented exclamations (the phrase "BULLSHIT ARTIST!" is uttered approximately 8,000 times), and gallons of grease. Not disturbing, just... disturbed. Take that as high praise.
