For years people wondered what Butthead meant when he called Beavis a "butt muncher." Then "The Human Centipede" came along to give popular culture a visual. Now, Eric Roberts has joined the list of actors who will be puckering up for next year's "The Human Centipede III (Final Sequence)."

Julia Roberts brother brings quite the resume to the shock horror franchise — he was in"The Dark Knight," "The Expendables" and a lot of TV movies. As Entertainment Weekly pointed out when they broke the "Centipede III" story, he's also got an Oscar nomination, thanks to 1985's "Runaway Train." As if going toe-to-toe with Batman wasn't enough, the supposed "Final Sequence" will put Roberts right in the center of a buzzy pop-culture series that is looking to once again up the ante in gross.

Centipede baddies Dieter Laser and Laurence R. Harvey are both set to return, alongside newcomers Tommy "Tiny" Lister (the dude who will knock you the eff out in "Friday"), Robert LaSardo ("Death Race") and ex-porn star/Charlie Sheen "goddess" Bree Olson. Tom Six will once again write and direct. This one is supposed to feature a (shudder) 500 person human centipede.

Maybe we'll even get to see Roberts do what he does best: Die.
