The more inbreeding in your bloodline, the further you'll go to seek sexual satisfaction. A simple concept, officially reinforced by whatever director's cut episode of Survivor Man is going on in that last clip. I'll put it this way; in comparison it makes Jeppson's Malort seem like a fucking delicacy. It's that abhorrent.
Farted on, finger raped, told he looks like fuckin Robin Williams - this dude endures pain you can't even imagine. Fortunately he's a Sum 41 mosh pit survivor and holds a blackbelt in making Terminator-esque sound effects whilst flailing his arms like a fucking idiot, so it's all good.
