I just saw Charlie Sheen's version where he dumps $10K in bills over his head and said that would be his donation. He challenged Jon Cryer, Chuck Lorre & Ashton Kucher to do the same. I gotta say it's inventive.
Oprah did the challenge then challenged Steven Spielberg, Manish Dayal & Helen Mirren to do the same. IMO, this was just Oprah advertising her co-produced movie, The Hundred-foot Journey. Not sure if I appreciate that.
