You know how you get to be a Comedian of Comedy? You have to be one of the funniest people alive. Three out of four of the original CoC's are doing sets, including Sub Pop signee Patton Oswalt, but Zach Galifianakis is missing, which is okay because Brent Weinbach is funnier—his sets at Bumbershoot were jaw-droppingly good. This is the kind of show I bring diapers to because I'm going to shit my pants so hard. (Showbox at the Market, 1426 First Ave, 628-3151. 7 pm, $20 adv/$25 DOS, 21+.)
