DSBPI recently screened the Miramax release of "Comedian," a documentary tracking Jerry Seinfeld's adventure in trying to build a brand new stand-up act after he retired all of his existing material on the HBO special "I'm Telling You For the Last Time." Beyond recommending the flick, DSBPI wonders why more celebrities and public personas don't take a lesson from Seinfeld: quit when you're on top, with your reputation intact. Seinfeld realized that he would never top "Seinfeld." He instead went back to his roots in the Comedy Cellar and Gotham Comedy Club, honing his stand-up craft. Perhaps Arnold could learn a lesson from Jerry. The Bushies would argue that you accrue political (and popular) capital for a reason: to spend it when needed. But for some reason I don't see Jerry running for Hillary's vacated 2008 Senate seat -- he just knows better when it's time to say "goodnight."
