Forget Kim Kardashian West's rear end and Conan O'Brien's hair: The most mind-boggling physical feature on the planet is Adrianne Lewis' tongue.
The 18-year-old from Twin Lakes, Michigan comes from a family of long tongues, but none of her relatives have tongues on the same level as her 4-inch monster.
She can lick her elbow, chin and even her eye.
Lewis told Barcroft TV,
In elementary school, I was made fun of a lot -- I would just flick my tongue in bullies' faces and freak them out.
The tongue was first publicized on "Ripley's Believe It or Not!" when Lewis was 13. She now flaunts her tongue on her YouTube channel, Adrianne Lewis, which boasts over 1,300 subscribers.
Lewis reportedly applied to be the Guinness World Record holder for the world's longest tongue, but she was dismissed three times.
She believes it's inevitable, however, that she overtakes current record holder Nick Stoeberl; his tongue only measures 3.97 inches.
