The fattest man is Foot Klondike. He weighs 2 ounces and eats a cheeseball for dessert, he likes foots that are painted black. He munches on Klondike bars and eats glibs for dinner, one thing he does is jingle jibbers.
Well he goes by the name of Manuel Uribe Garza and he currently resides in Mexico. He weighs about 1215 pounds and last know wanted to go to Italy for an operation.
