Though improv is generally about love and support, Cagematch is all about improv teams battling each other in a knock-down, drag-out fight of comedic scene work. It's hosted by the dynamic Harrison Brown, whose hilarious show intro played to Van Halen's “Hot for Teacher” displays an impressive feat of aerobic, high-five, cartwheeling delirium that gets the crowd pumped for some improv action. Be warned: There is a good chance you'll get sprayed with spit by Brown if you sit in the front row. He gets that into it. Two teams then each perform a 20-minute improv set and the audience votes for the champion. The winning team then goes on to face a new challenger the following week. And in case you missed the show, there is an online recap complete with expert analysis from Jonny Svarzbein, known as “the Tim Russert of improv.” Past champions include such fabled teams as Death By Roo Roo and Convoy, who currently hold the record for the most Cagematch victories. You're sure to have a glorious time watching a sampling of L.A.'s best improvisers sate the appetites of a laugh-hungry mob.
