If the constant repeats of “Seinfeld” in the past 10 years since the show stopped producing new episodes have left you wanting more, why not check out the comedian when he comes to the Dodge Theatre on June 6? I used to have much of his old stand-up act memorized (”You don’t see me knocking on the cockpit and saying ‘I’m having the peanuts now!’”), not so much because I was such a big fan (even though I did enjoy the show), but just because it was the same jokes over and over again every time he was on TV and all that. But they were great! But now, I guess he has new jokes, that’s what that documentary was all about, right, so hopefully they’re still pretty funny. Maybe now he has cutting-edge material on text messages or social networking Web sites! What is the deal with Twitter?
