"Fox News channel talk show host Bill O'Reilly says 'shut up' the way other people say 'um,'" observes Jack Shafer. "On his daily show, The O'Reilly Factor, he uses it as a place-holder for an idea still formulating in his brain. As a way to begin a sentence, end it, or punctuate it. ... He's even heaved this impolite language at entire nations, demanding they recuse themselves from the international conversation. In the half-decade his top-rated show has been on the air, he's called for the muzzling of practically everybody. At the rate O'Reilly is going, he'll be the only person allowed to speak in a couple of years."
