I had forgotten almost completely that there was once, about twenty years ago, a thing called “alternative comedy,” which seemed about to break out and become part or even most of the mainstream practice of standup as “alternative music” (though by then it was already rare to hear it so referred to) had done with mainstream radio. That didn’t happen. Standup, today, is still mostly made of jokes. Not that there’s anything wrong with that. But Janeane Garofalo, it turns out, is still going around doing a different thing, talking, being weird, looking at notes, enjoying herself. People laugh.
