CULLMAN, AL—In the past three months, John "Jenko" Quigley, 26, has casually consumed 276 pounds of pepperoni-pizza-flavored Combos snacks, an amount equal to his own body weight. "Actually, Jenko weighs almost 300 pounds now, but he was 276 when he started around New Year's Day," friend Darrell Nenn said Monday. "Guess all those bite-sized pretzels with cheese-flavored filling can really pork a guy out." Quigley said he began eating the popular snack food to curb his appetite between meals, but continued long after his hunger was cheesed away.
