Yep, and that's why he should be sitting right where he is.
Honestly, he's smart enough to know the responsibility that comes with having those two letters in front of his name (they even teach that in medical school). Add to that the validation presented, not only by having a TV show, but by having one sponsored by Oprah - and he ought to know better.
He could just as easily have spent his time explaining how there is "no one perfect diet" (like he did to the committee) to housewives. They're the ones who really need to hear it. They need to hear "talk to your doctor" and "get regular exercise" not "here, take this!" Just how many of his viewers will bother to watch this clip?
