A very entertaining read.

I'll start with the critiques first because I have more praise for this story than criticisms. Some of the paragraphs did run a bit long. Stuff like that becomes an eyesore after a while. Breaking it up into smaller paragraphs will make the read more easy and pleasant on the eyes. Just my personal recommendation.

Anyways, I really enjoyed this alternate timeline you created where Butt-head literally knocked some sense into Beavis and changed the structure of their lives. I liked how Stewart finally stood up for himself and had Beavis become his adopted brother. I also find it ironic that after all those years, Todd finally allowed Butt-head to join his gang(despite still having limits). In some ways, it's fairly appropriate for this to happen to him while Beavis moves on with his life and becomes successful. I liked how Butt-head finally encountered Beavis, only to have his and Todd's ** kicked.

My favorite line had to have been this:

"But Beavis was a former Football player, a marine, big and muscular enough to kick everybody's ** and he had a wife and two children which meant that he scored at least two times, maybe more."

Uh yeah, Butt-head. I'm sure Beavis has scored far more than "at least two times." I nearly spilled my drink laughing when I saw this line about how Butt-head assumed that Beavis had scored at least two times or "maybe more." After all these years, he really is still that clueless.

Anyways, this was an excellent oneshot. Although to be honest, I'm kind of disappointed Van Driessen, McVicker, and some of the other main characters didn't make any appearances. It would've been interesting seeing how Van Driessen and McVicker would've reacted to the new-and-improved Beavis. But still, the story by itself is excellent even without the other teachers(speaking of which, it would really be interesting seeing Daria's reaction to Beavis... but then again, she probably is in Lawndale at this point).

Overall, good job.
