Beavis and Butthead DO America - drink a six pack (necessary) turn on the movie and laugh your ass off for an hour or so. And it's got some pretty good voice acting from the likes of the guy that played Elliot Ness on the tv show, Bruce Willis, Demi Moore and others.
Funny, funny movie if you don't take life too serious and got a few beers in ya or some other kind of buzz on when you watch it.
