Sean Hannity, the ball is in your court.

Last night on Countdown, Keith Olbermann took the FNC host up on his offer, made Wednesday on "Hannity" in a discussion with Charles Grodin, to get waterboarded for charity.

"For every second you last, $1,000," said Olbermann. "Live or on tape, provided other networks' cameras are there, $1,000 a second, Sean, because this is no game. This is serious stuff. Put your money where your mouth is, and your nose. Oh, and I'll double it, when you admit you feared for your life."

Guest Lawrence O'Donnell added fuel to the fire. "The reason Sean Hannity thinks torture is a good idea, the reason he thinks it works, is because it would work on him," he said.
