Oh, Matt. He's slept with a transsexual, a Nazi, a porn star, a suicide-bomb victim, and [now] his half sister. Maybe the dude should try Match.com?
The porn star was also his father's ex-girlfriend, the victim of a serial rapist, a Scientologist and a crack addict.
John Hensley plays Matt.
In the film Teeth, Hensley's character sleeps with his step-sister, whose mutant vagina bites off part of his dick and inadvertently feeds it to his dog.
