Is Beavis and Butt-head still relevant? Last night’s premiere of the revived MTV classic took aim at 16 and Pregnant, Jersey Shore, and the vampire/werewolf craze, in the show’s trademark mock-ignorance and disdain. (“Why is everyone’s mouth always open?” is probably the greatest criticism of 16 and Pregnant ever.) But B&B are far from the only ones taking shots at the dumber aspects of pop culture, and at a time when jokey criticism is the currency on which the Internet economy is based, are Beavis and Butt-head still part of the conversation? Now that the show doesn’t feel scandalous — and it doesn’t — is it really the same old Beavis and Butt-head? What did you think of the show last night? Do we still need Beavis and Butt-head? Do you still want them?
