I keep dreaming of a "BnB in their twenties" type of show. Beavis would be a male prostitute, Butthead would live off of him and just abuse and exploit him in general.
They covered this in one of the Christmas Specials! "It's a Horrible Life."
Basically, an angel was trying to convince Butthead how much better the world would be if he had never been born. Beavis ended up being a lot nicer, though he was still subservient to new alpha male Stuart. (the kid couch fishing with them in this clip.)
I love the Christmas episode for those moments exactly. But I like to think that hanging out with Stuart and going to church groups, Beavis might have been able to get the help he so badly needed.
