I saw Jerry Seinfeld at Caesars Palace Las Vegas on Jan 30, 2009 and I wasn't impressed. He just wasn't that funny. It totally ruined my perception of him. However, his opening act was awesome. I'm not sure, but it could have been comedian Tom Papa as the opening act. I'd see Seinfeld again only if the tickets were free and I just wouldn't expect much. HUGE disappointment. Save your money or go see Celine Dion, Bette Midler, or Jeff Dunham instead.
