The widest mouth measures 17 cm (6.69 in) and belongs to Francisco Domingo Joaquim “Chiquinho” (Angola).
It was measured on the set of Lo Show dei Record in Rome, Italy, on 18 March 2010.
He can fit a whole can of pop in his jaws sideways and has been recognised as having a world-record sized mouth.
Francisco Domingo Joaquim’s 6.69 inches wide rubbery yap has earned him the bizarre title of the ‘World’s Widest Mouth’ by the Guinness Book of World Records.
The 20-year-old, who is also known as the Angolan Jaw of Awe, put his elastic skills to the test at the the ‘Big Mouth’ competition in Rome this month.
Contestants crammed their cake holes with a whole host of items including saucers, coffee cups and beer bottles but nobody’s mouth could beat Francisco and his can of coke.
He shot to stardom performing his jaw-dropping talent on the streets of Luanda, capital of Angola, and even performed on an Italian TV show, popping a can in and out of his mouth 14 times in one minute.
Francisco, known as Chiquinho, was discovered by Guinness Book of World Record researchers scouring YouTube.
After two years of searching, they tracked him down to his hometown in Angola.
Since then Francisco has become an Internet sensation with his videos racking up thousands of hits.
Joaquim said it was a ‘dream come true’ to be honoured by Guinness World Records.
