Judge of the Guinness World Records Lorenzo Veltri checks the length of a pizza at the Expo 2015 world's fair in Rho, near Milan, Saturday, June 20, 2015. More than 60 of Italy's best pizza-makers worked through the night to create a 1.59545 kilometers, or nearly a mile long pizza at Milan's world fair. Their toil was rewarded with a proclamation by Guinness World Records judge Saturday that it was the world's longest pizza. Expo organizers said the record-setting pie, made with 1.5 tons of mozzarella and 2 tons of tomato sauce, weighed some 5 tons in all. (Daniele Mascolo/ANSA via AP)
