This was the first episode of Season 3. The animation is now a lot cleaner than it was in the last two seasons. Also, Beavis and Butt-head's voices have been altered. Despite the changes, it didn't stop Season 3 from becoming one of the best, if not, the best seasons in the show. This episode started Season 3 off litterally with a bang...but unfortunately, it got banned because it had an enourmous series of fire references.
The good news is, there's an uncensored version of it on Youtube. http://youtube.com/watch?v=HkCr5U50vdI
It has its moments, but wasn't entirely what I expected. Still, it's funny.
