I saw on him the Drew Carey show a few weeks ago too. I had to do a double take, couldn't believe how much weight he had lost.
Wayne Knight was in "Cheaper by the Dozen" in an uncredited role (as was Ashton Kutcher) and he was thin in that. I recognized him but had to look it up for sure because I was amazed at how thin he was in that movie.
Hard to believe Ashton Kutcher's role was uncredited since he was in the trailer. I assume some sort of F. Murray Abraham-type thing happened.
It's amazing what eating right and lugging a rickshaw through the streets of New York will do for you.
