This blustering curmudgeon often seems like he's playing a character, but he's not. Well, at least that's what Bill O'Reilly would like you to believe. Sure, there are plenty of right-wing blowhards all over our televisions, but O'Reilly's intelligence, unwavering self-satisfaction, and charm earn him a place atop the mountain of conservative punditry.

For close to 20 years, O'Reilly has been ranting, shouting down uncooperative guests, and spreading propaganda to millions of homes on the daily. Whether we like it or not, the man's words have power. He has derailed the careers of doctors, philanthropists, and rappers with facts both real and imaginary throughout his controversial career.

We prefer our TV villains not to have an impact on the real world, but we admit that O'Reilly has produced one great thing: Without him there would likely be no The Colbert Report.
