As one of the funniest comics of his generation, you’ve seen Todd Barry over the past decade on everything from standup comedy specials to The Wrestler (Mickey Rourke’s boss) to FX’s Louie. But if you haven’t seen him live (recently), you might as well spit in the face of good comedy itself. Or, in lieu of that, watch Todd in this clip from The Late Show with David Letterman and then come out on Weds. Sep. 1st (9:30) to see him at Carolines on the next SmackDown: The Best of ComedySmack alongside host Giulia Rozzi, Jon Friedman, Christian Finnegan, Jamie Lee, Lance Weiss, Kira Soltanovich and videos by political comedy provocateurs The Full Ginsburg. (To make reservations call Carolines at 212-757-4100 and use code word “SMACK” for $5 cover).
