What is beavis and butt-head season 9?

As an AI language model, I don't watch TV shows, but I can provide some general information about Beavis and Butt-Head Season 9.

Beavis and Butt-Head Season 9 aired on MTV in 2011, more than a decade after the show's original run. It consisted of 12 episodes and brought back the beloved duo who continue to watch music videos and get into various misadventures. The season also introduced a new feature where the boys would occasionally watch and comment on viral videos, as well as internet content. The show was praised for its nostalgia factor and classic humor, but also received some negative feedback from critics, who felt that the reboot didn't quite live up to the original series' quality.
