"Beavis & Butt-Head," "Good Vibes" get supersized

Viewers are in for a special two-hour animation block, with all-new back-to-back episodes of Mike Judge's Beavis and Butt-Head at 10 and 10:30 p.m. ET/PT, followed by two new episodes "Good Vibes" airing at a special time, at 11 and 11:30 p.m. ET/PT, this Thursday, December 1 on MTV.

On Thursday night's episode of Beavis and Butt-Head airing at 10 p.m., a fool and his nachos are soon parted... by a rat? When a rat takes up residence in Beavis and Butt-Head's kitchen, they'll stop at nothing until the kitchen at Burger World has one, too. Then, filthy chicks at the beach! An oil spill draws hot hippies to the shoreline, and Beavis and Butt-Head try to get eco-friendly with these granola girls. But when all the "filthy chicks" are taking wing, will the boys see the value of dirty work, or are they just too crude?

Then later, in a new bonus episode of Beavis and Butt-Head airing at 10:30 p.m., it's the end of the world as they know it, and Beavis and Butt-Head feel fine. When the apocalypse leaves them behind, Highland's biggest idiots have run of the town. Will they finally score? Not even when they're the last men on earth. Then, when a religious group encourages them to take a stand against a science lesson, these brain-dead idiots take the cue to check out. They can't get a clue, but will they get religion just to get out of class?

On this week's all-new episode of Good Vibes airing at a special time, 11 p.m., Mondo takes a "Polar Bear Plunge" racing through freezing water, but afterwards accidentally drops trou and humiliates himself. The next day, Milan unveils a mean school tradition: The D-List, which ranks the very thing that Mondo unfortunately exposed to the whole school -- and now, he's at the bottom. To make matters worse, Woodie is at the top, a spot that causes a rift in his friendship with Mondo.

And in a special second original episode airing at 11:30 p.m., Jeena launches a mobile breast exam initiative, spurring Mondo and Woodie to cross dress in an attempt to feel some lady-parts consequence free. Let's just say not every girl in Playa Del Toro looks like Jenna, and they learn all too quickly that second base doesn't come free.

In 1993, Mike Judge (creator of Beavis and Butt-Head) and MTV knocked their heads together and launched a cartoon series starring a couple of lunkheads and unwittingly started an animated pop culture revolution. Now, Beavis and Butt-Head are back on MTV to unleash upon music videos, Jersey Shore, viral videos and more.

Good Vibes follows transplanted Jersey boy Mondo (voiced by Josh Gad, The Book of Mormon) and his best bud Woodie (voiced by Adam Brody, The O.C.), as they surf the biggest waves, hit the wildest parties and chase the prettiest girls in Play Del Toro -- a colorful California beach community.

The all-star ensemble cast also features Debi Mazar (Entourage) as Babs, Mondo's mom; Alan Tudyk (Suburgatory, Serenity) as Lonnie, a burnt-out but wise beach bum; Danny McBride (Eastbound & Down) as Ms. Teets, a massively overweight and inappropriate human sexuality teacher; Olivia Thirlby (Bored to Death) as Jeena, the beautiful girl of Mondo's dreams; Jake Busey (Starship Troopers, The Good Guys) as Turk, an obnoxious local surfer and bully; and Tony Hale (Arrested Development) as Wadska, a charmingly nerdy and delusional friend.

Good Vibes was created by David Gordon Green (Pineapple Express, Your Highness) and is animated by Six Point Harness. Along with Green, executive producers are Tom Brady (The Simpsons), Tom Werner (Roseanne, That 70's Show), Mike Clements (Life and Times of Tim, Are You There Vodka, It's Me Chelsea) and Brad Ableson (The Simpsons).
