Written and directed by Cash Markman, who is also responsible for the seventh entry on this Top 13, Throbin Hood: Prince of Beaves is a clever spoof of the 1991 Kevin Costner hit Robin Hood: Prince of Thieves. Indeed, the title is certainly fitting and the plot isn't that far off of the original. In this tale of epic contortions, Throbin Hood and his Merry Men try to rescue Maid Mary Ann from the evil Queen Caroline and Sheriff Naughty Ham. Plus, porn legend Ron Jeremy plays Friar Fuck.

Like Throbin Hood, this film remains relatively true to the target of its parody, Stanley Kubrick's sensational cult classic A Clockwork Orange. Just like in the original, A Clockwork Orgy features a gang leader and (in a necessary alteration) her three droogs, all clothed in the same bizarre white unifoms and black hats. Even the dialogue is similar. And while Alex from Kubrick's film prefers Beethoven and ultra-violence, Alex from Nic Cramer's version simply desires sex. The must-see trailer below features no nudity or sex, though it does show a woman in somewhat revealing lingerie.

A spoof of A Clear and Present Danger, it's no surprise that this film can't match the fast-paced plot and intrigue of Tom Clancy's novel from which the original was adapted. Nevertheless, A Rear and Pleasant Danger writer and director Mitch Spinelli picked a perfect title to convey the thrust of his film and even managed to mix in a case of mistaken identity and a little danger to make it a bit reminiscent of the Harrison Ford blockbuster.

This spoof of Tim Burton's fantastic classic Edward Scissorhands almost seems too easy. Just replace Johnny Depp's scissors with Sikki Nixx's penises and voilà, you have porn. But writer/director Paul Norman does a better job than most on this list in sticking to the send-up. Watch a few scenes from the porn version below. Warning: there's certainly no sex or actual nudity, but the protagonist's absurd penishands are central to the clip.

The only film on this list to target a family film, this titular spoof of the Rick Moranis flick Honey, I Blew Up the Kid, is, according to its producers, "the story of a girl who just couldn't say no." While Wayne Szalinski invents a machine that make his kid a giant in the Walt Disney film, Honey, I Blew Everybody's Tiffany does exactly what the title suggests - as do all the other women in the film. Like the original, the porn version was part of a franchise, spawning several sequels.

This is the first of two films on this list from Wicked Entertainment, one of the dominant players in the porn industry and the company that gave the world the legendary Jenna Jameson. Terms of Endearment is a critically-acclaimed tear-jerker, which won five Academy Awards (including for Best Picture). Sperms of Endearment, on the other hand, is about a whole different kind of jerking.

This play on Star Trek: The Next Generation was actually a spoof of the original Star Trek series, but that's really irrelevant for our purposes. The porn title works perfectly, nevertheless, in foreshadowing the hilarious storyline. The crew has discovered life on the planet - you guessed it - Uranus. But the beings Captain James Quirk and First Officer Mr. Sperm find aren't your garden variety aliens; instead, they're foul-smelling, sex hungry female humanoids. We're sure you know what happens next. The phenomenally acted clip below is nudity-free.

Other than the witty title, this film has little in common with the big budget John Carpenter movie from which it takes its name (though producers did, at least, cast an Asian actress). The company behind Big Trouble in Little Vagina trumps its casts of petite cuties who prefer, to put it gently, well-endowed men. It's a far cry from Kurt Russell's starring turn in Big Trouble in Little China as a truck driver who tries to help his buddy rescue his girlfriend in San Francisco's mysterious Chinatown underworld.

Just like Woody Allen wrote and directed the fantastic dramedy Hannah and Her Sisters, which tells the inter-related stories of an extended family over a two-year period, C.C. Williams wrote and directed this ingeniously titled spoof about the three Hott sisters who join with their family to mourn the loss of Hannah's pet, Muffy. This film features precisely the kind of family togetherness that Woody Allen himself might appreciate.

Oliver Stone won the Academy Award for Best Director for his Tom Cruise-starring 1989 adaptation of veteran Ron Kovic's autobiography that depicts the devastating impact of the Vietnam War. While Born on the Fourth of July is a powerful film full of emotional heft, the Gordon Vandermeer-directed spoof is simply full of sex. As the producers of the film explain, the main character is "hotter than a firecracker" and "explodes with a display of passion that could only be Porn on the Fourth of July."

When spoofing one of the highest grossing films of all time, it helps not to stray too far from the original's plot, and that's sort of what The Da Vinci Load director Jerome Tanner does in this absurd takeoff of Ron Howard's The Da Vinci Code. In the Tom Hanks film, clues in Da Vinci paintings lead to the discovery of an ancient religious mystery kept secret by the Priory of Sion sect. Here, operatives of the Priory of Semen discover a secret of their own - that Da Vinci painted the Mona Lisa using his own sperm. Watch the aptly named Professor Lee Teabag explain how the Da Vinci Load can be obtained in a non-pornographic clip below.

The second film on this list from Wicked Pictures, Good Will Humping is, as it sounds, a spoof of sorts of Gus Van Sant's 1997 Academy Award winning Good Will Hunting, which was written and starred in by Matt Damon and and Ben Affleck. While the original boasts Damon as Will Hunting, a South Boston hooligan and prodigy who takes a job as a janitor at MIT, the porn version offers 19 full-length sex scenes over a staggering 243 minutes.

In M. Night Shymalan's fantastic breakthrough The Sixth Sense, a child psychologist tries to help a nine-year-old boy who claims to see dead people who don't know they're dead. Well, Michael Danze's The 69th Sense isn't all that different. Psychologist Dr. Dick Harden's beautiful patient Jenny also sees dead people - albeit horny dead people - and Jenny needs to use her "69th sense" to help them fulfill their deepest sexual fantasies so they can move on to the afterlife.
