On April 23, 2007, the world was blessed with the premiere of a show that would change the Food Network forever: Diners, Drive-Ins and Dives. Guy Fieri's "chill bro" demeanor won over the hearts, stomachs, and collective indigestion of an American populace looking for greasy roadside eats they didn't even know they needed. And after 10 years of episodes (and a one-off special in 2006 that predated the show itself), some things haven't changed -- namely Fieri's unnaturally bleached, spiky coif. It's weathered everything from numerous visits to diners and dives (and all of two drive-ins), many rounds of grocery games, and a Donkey Sauce-coated life. To celebrate this not-unimpressive feat, we look back on a decade of Guy Fieri and his gravity-defying, gelled-up hair. Join us!
