‘Beavis and Butt-head Do America’

This 1996 winner brings to the big screen those no-brainer nerds who have brought laughter to living rooms around the world for nearly four years. There’s been much analysis of the appeal of the two geeky early-teen virgins who are fueled by raging hormones and who’ll say anything, much of which is crude, that pops into their empty heads. Yet it seems simple enough: They reassure us that there could be unthinking people out there who make mistakes more stupid--OK, as stupid as--most of us do, and they’re usually hilarious while doing it. Of course, with their total lack of inhibition, they’ll say things that many people feel but wouldn’t dare to express, which allows for a satirical spin to their exploits and utterances. “Beavis and Butt-head Do America” has a great look, placing the boys, drawn in a symbolically rudimentary style, against backgrounds deftly evoked with minimal fuss. Their creator, Mike Judge, who also provides the gurgly voices of both guys, and his co-writer Joe Stillman imaginatively send the duo off on cross-country adventures all because someone stole their TV set (HBO Saturday at 8 p.m.).
