Cheaper Than Therapy lets San Francisco's cleverest (and, yes, craziest) comic minds uncork in an evening of comedy and catharsis. But the benefits aren't limited to those on the stage. As the punchlines pile on and the room starts to crack up, you might discover that laughter really is the best medicine. Produced by the formidable comedic duo of Eloisa Bravo and Jon Allen, Cheaper Than Therapy offers a prescription-only dose of hilarity. Surely no treatment regimen is as enjoyable as this hilarious event at the Shelton Theater.
