The sniggering, hard rock-loving duo are back trying to pull girls and dishing out childish put-downs at music videos and MTV's finest trash TV. ("I've seen every episode of Teen Mom season one and two... hur-her").
To celebrate the show's return, Digital Spy previews some of the best zingers from episode one.
Beavis & Butt-head on Twilight:
"Is Bella a zombie? She is always just standing there with her mouth open and she acts like she's dead."
"How come everyone whispers in these movies... They're probably embarrassed."
"How come chicks like this crap?"
Beavis & Butt-head on MGMT's 'Kids' video:
"What kind of parent puts their kid in this video? Alright son, there's going to be some scary monsters and some creepy people putting their hands on you. But you should be able to handle it, you're 1 and a half now."

Beavis & Butt-head on LMFAO's 'Champagne Showers':
"This is like the same dance they did in 'Party Rock Anthem', except they're pretending to choke their chickens in it."
"The economy sucks, nobody has jobs and these guys are just spraying champagne around everywhere."
