When you reach 5,000 episodes, you deserve a celebration, so Jeopardy!, that game show of a certain age, will do it up big with two weeks of Celebrity Jep. TV Guide has learned that among the 30 names hitting the buzzers for charity for November-sweeps broadcasts are hopefully smart-and-nimble Desperate Housewives guys James Denton and Doug Savant, Law & Order franchisees Sam Waterston, Christopher Meloni and Kathryn Erbe (all competing against each other), Anderson Cooper, Rachael Ray, Paul Shaffer, Martin Short and Regis Philbin, who says he wants to make up for the "broken buzzer" he had during his last time on the show.
