Anthony Bourdain vs. Paula Deen
Chef Tony isn't shy with his words, and in 2011, he called Deen (who's known as the Butter Queen) the "worst, most dangerous person in America" for promoting her fattening recipes to an already obese nation. Shortly after, when it was revealed that she had been hiding her Type 2 diabetes diagnosis for several years, Bourdain said, "When your signature dish is hamburger in between a doughnut, and you've been cheerfully selling this stuff knowing all along that you've got Type 2 diabetes ... It's in bad taste if nothing else."
