Kendall Jenner Eats a Real Crocs Clog on ‘Tonight Show’ (Video)

And a Rubik’s Cube

Food or not food? That is the question Jimmy Fallon and Kendall Jenner attempted to answer on Thursday’s “Tonight Show” — and it didn’t always have a delicious answer.

Fallon, who is a self-professed Japanese game show buff, concocted this challenge for himself and the “Keeping Up with the Kardashians” star/supermodel in which they had to guess if everyday objects were real or made of food.

Jenner made the wrong call in round one, when she chomped on a bright yellow Crocs clog that was definitely just a bright yellow Crocs clog.

“Nope!” she said, as soon as she tasted it. “Definitely rubber! Definitely rubber.”

Jenner also hoped aloud the Crocs were new — but Fallon wasn’t actually sure.

In the next round, Jimmy guessed a phone wasn’t really a phone and was treated to a chocolate electronic instead that he says was  “actually really delicious.” Oh, and Kendall agreed.

In the final round, Jenner was stumped yet again by a particularly appetizing-looking Rubik’s Cube, which was really just a toy. In reality, Mr. Potato Head was food. Was that one a little too on the nose?

Gah, our teeth hurt just watching all of this apprehensive chewing.
