Believe it or not, but this is not a manipulated photo- nor is it an optical illusion. His name is Francisco Domingo Joaquim from Angola and he is the proud owner of the title “World’s Biggest Mouth”. His mouth measures 17 cm (6.69 inches), which was measured on the set of Lo Show dei Record in Rome, Italy, on 18 March 2010. His “jaw dropping talent” (pun intended) was discovered by Guinness Book or Records researchers who were scouting Youtube for new talent. After a two year search- they were finally able to catch up with him and officialy measure his massive mouth. Pretty bizarre huh?
