The return of Who Wants To Be a Millionaire is upon us, and with it, its requisite buzz factory. ABC announced today that the revival will include celebrity guests. Festive! Every night of the two-week run, a different celebrity will answer a single question to win $50K for the charity of their choice. That’s two fewer questions than you need to answer to cross a bridge, for those of you keeping score at home.

And then there’s the line-up of noted celebrity intellectuals: Lauren Conrad, Snoop Dogg, Patricia Heaton, Shawn Johnson, Steve Nash, Katy Perry, Rachael Ray, Sherri Shepherd, Vanessa Williams, Wynonna… and a “Surprise Guest.” None of these celebrities particularly screams “trivia whiz” to me, but the allure of a surprise guest is irresistible.
