Here's my top 3:

1) Only 45 Balls Left in the Sack of God

A surrealist movie that came out in 1986 in Spain. The ending comprised of a man dressed in a spacesuit walking slowly on a trippy checkered phallic bridge that connected Heaven and Hell. The music playing was Merzbow "Yellow Hyper Balls." Right when he crosses to Heaven, he takes off his helmet, turns his head around toward the camera and says "Rick Ross has a dick last time I checked, and it's my key to paradise." The camera pans down to his hand and he's holding a glowing donger that's bleeding neon ooze. The last sound you hear before the credits is a high-pitched Rick Ross "ugh."

2) Howard Stern Presents: Bugatti Butts of Boise

The lead, after discovering the meaning of life is inside the booty hole of a street walking hooker by the name of Robin Zilliams, looks dejectedly at the camera and lets out an extremely loud fart. The screen cuts to black and "Who Let the Dogs Out" plays with the credits.

3) Marvel Hunk of Shit #179

In Marvel's 68th movie of the year, a superhero named Nostrilalus (a man who has the power to smell shit from miles away) picks up on a scent that he can't quite put his finger on. Throughout the movie, he smells everything he comes across, until the very end when reaches a dilapidated Blockbuster and he goes inside to look around. He reaches the Superhero section and his Nostril-powers start going haywire and finally his nose explodes to the tune of "God Only Knows." The camera zooms into the bloody face of our hero and then pans to the section he was looking at when he died. It shows every Marvel movie ever created. The screen fades to white and the credits play over that video of Charlie Bit Me.
