Believe it or not, this is a real photo and not an optical illusion. This guy 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 huge talent (pun intended) was discovered by Guinness Book of World Records or researchers who were scouting Youtube for new talent. After a two year search they finally caught up with him and officially measured his massive mouth.
