It read, "You don't challenge a wizard." It was an obvious cross-reference between the fictional Wizard in the Wizard of Oz and Dr. Mehmet Oz.
In response, I impulsively wrote, "He's not a real wizard. He just plays one on TV."
After writing my response, I started thinking about the similarities behind the Wizard in the Wizard of Oz and the actual Dr. Oz.
Unlike the Wizard, Dr. Oz does not hide behind a curtain and use smoke and mirrors to impress his audience. Instead, on an almost daily basis he blatantly engages his audience with new secret cures and potions.
However, both characters do pretend to be something they are not. The Wizard worked hard to create the impression that he was all powerful, which turned out to be an illusion. Dr. Oz pretends to have magic pills and miracle cures, to have powerful remedies to jump-start diets and create lean bellies, to make wrinkles disappear and treat dementia, which also all turn out to be illusions. So maybe we would all be better off if he actually hid all those supplements behind a curtain.
They say that life sometimes imitates art. Has there ever been a better example than the Dr. Oz show?
