Dr Oz and Dr Phil are not doctors and should be to the left and south of Dr Pepper. Neither has a license and both are so full of shit their advice has probably killed people.
Oz is a Doctor, and was a very good one who got corrupted in his aim for fame and fortune. Part of his tragedy is that if he'd shut up and just do his actual doctor work only he'd be a benefit to society, not the detriment he is now. It's important to know that he's worse because he had actual skill as a heart surgeon. Quoting wiki:
In 1982, he received his undergraduate degree in biology magna cum laude[3] at Harvard University.[31] ... In 1986, he obtained MD and MBA degrees from the University of Pennsylvania School of Medicine[30] and Penn's Wharton School.[34][35]
Edit: also, as far as I can tell, still performing heart surgeries, so should still be licensed. Still a piece of shit who should stick to surgeries. Lots of people good at 1 thing think they're geniuses at everything.
