Battle of the Bands is the "punk rock" episode of CHiPs. In case you didn't already know, punk rock is evil, dangerous music, and if it wasn't for helpful TV shows of the '80s like this and Quincy, we would all surely be dead.
This episode guest stars William Forsythe as a punk rocker named Trasher. Trasher and his band steal some instruments and cause some mayhem, but the real fun begins when they cause a riot at a local battle of the bands that Ponch happens to be performing in. At one point, Trasher flicks a lighter, then the show cuts to commercial as he laughs like a maniac. And that, friends, is great television.
