The biggest mouth in the world?
That's what the Guinness World Records Commission says...
In the Guinness Book of Records, we find many such and different excesses, and one of them is the mouth of Isaac Johnson, a boy from Minnesota, USA. They are so big that they have been declared the biggest mouth in the world.
Isaac won the title for the first time in December 2019 when he was 14 years old. At that time, his mouth opening measured 9.32 cm. But the record did not hold for long, as only half a year later Philip Angus from Pennsylvania surpassed it with 9.52 cm. But Isaac "didn't give up", he kept growing (or stretching) and regained the title a few days ago. This time's measurement by the Guinness Commission showed that it can open its mouth as much as 10.175 cm.
