A Minnesota teenager broke his own Guinness World Record when his mouth gape was measured at 4.014 inches.

Isaac Johnson originally set the record at the age of 14 in 2019, when his mouth gape was measured at 3.67 inches.

Johnson’s record was broken later the same year when Phillip Angus of Pennsylvania opened his mouth 3.75 inches.

Johnson reclaimed the record in 2020 when his gape was measured at 4 inches, and he broke his own record this year when adjudicators measured his gape at 4.014 inches.
