IGN - Season eight of Beavis and Butt-head is coming to a close, with only three scheduled episodes left. This week's episode, like most of this season, was a great success. "Time Machine" is the first short. It finds Beavis and Butt-head on a school trip. They fall asleep on the bus ride and wake up in a faux living community set in the 1800s. After some disorientation, they simply accept the fact that they've somehow traveled back in time.
