5. A Corpse
As seen in: Clerks (1994)
Refusing to leave any ground uncovered when it comes to shunned sex, Clerks writer-director Kevin Smith proves once again that he's not afraid to tackle the taboo when Dante's unlucky lady friend Caitlin (Lisa Spoonhauer) enjoys a dirty dalliance in the bathroom with a recently-deceased masturbator, who she mistakenly assumes to be her man.
Sadly for her, after recapping every last steamy detail, her ex breaks the news that he'd never been inside (ahem), causing a massive freak-out. Hey, at least it seems her new friend went out with a bang. Heyo!
