The world's largest peanut butter and jelly sandwich was created in Oklahoma City, OK, on September 7, 2002, by the Oklahoma Peanut Commission and the Oklahoma Wheat Commission. The PB & J sandwich weighed in at nearly 900 pounds, and contained 350 pounds of peanut butter and 144 pounds of jelly. The amount of bread used to create the sandwich was equivalent to more than 400-one pound loaves of bread. Now that's one giant sandwich!
