Everyone loves cold pizza and it's safe to say this pie probably had a few slices left over.

Nearly seven dozen chefs came together in Milan last weekend to make the world's longest pizza, at 1.59545 kilometers long. That's just under a mile.

The pizza needed one-and-a-half tons of mozzarella cheese, two tons of tomato sauce, 5,500 pounds of dough and 3,800 pounds of flour. After about 18 hours, the pizza was ready.

The pizza topped the old record of 3,700 feet, set in 2011.

Perhaps the best part of this mouth-watering record? People who were on hand got to eat the pizza for free. Better that than getting it for delivery. No car could fit all that pizza inside it.
