When it comes to wolfing wings, Sonya Thomas is a wiz. The 105-pound (48-kilogram) competitive eater who goes by "The Black Widow" bested a dozen beefy rivals Saturday night, scarfing 173 wings in 12 minutes to win the wing-eating contest at the National Buffalo Wing Festival. "That's 5.17 pounds of wings," said Brian Kahle, spokesman for the annual event in the city where Buffalo wings were born. In metric, that would be 2.35 kilograms of wings. Thomas, 40, who is originally from South Korea and now lives in Alexandria, Virginia, also held the festival's previous record of 161 wings in 12 minutes, set in 2004. "She's the crowd favorite," Kahle said. "It was 12 huge guys and her."
