First, Anna and Elsa are nice and calm and sweet. Beavis and butt-head are naughty and ridiculous. Second, they wouldn't get along. So it's not gonna be a success... but it's a GREAT idea for a theme for the "mad" tv show from cartoon network. It would be cool there. But, for a episode of beavis and butthead, not a successful moment. It's just my opinion.
