The annual World's Ugliest Dog contest went down on Friday at the Sonoma-Marin Fair in northern California. This year's champ may not be the ugliest winner ever . . . but she IS the largest. The winner is a three-year-old Neapolitan Mastiff named Martha. She's 125 pounds and her signature feature is her ENORMOUS, drooping jowls. Her owner gets $1,500 and a trophy.
