1. Beavis vs. Butthead 2. Backstreet Boys vs. 'N Sync A huge fandemonium. Fight Summary: 1 - Beavis vs. Butthead Beavis drinks too many beers and turns into Cornholio... Too drunk from the beers, he slices up Butthead. 2 - Backstreet Boys vs. 'N Sync This fight covered both the second and the third part of the episode, the second part when Nick resurrected them from the dead, and the third part was the fight itself. Here's how it turned out. The Backstreet Boys and 'N Sync each formed a special attack form: 'N Sync by holding each other together and forming a wheel, and Backstreet Boys by forming themself into a giant beast... this is hard to explain... The Backstreet Beast was way superior to the 'N Sync pinwheel, and the beast grabbed Joey and threw him into the wall, crushing his head. But Justin and Chris shocked the beast to death by using some electric wires.
