Scarlett Johansson says Chris Hemsworth is ugly and he suggests she’s not so smart.

Those are a few of the burns the “Avengers: Endgame” stars throw at each other in a tongue-in-cheek BBC Radio 1 game called “Playground Insults,” where the point is to see which participant can make the other laugh.

“You’ve got a growing collection of of grandma cardigans,” Johansson says to Hemsworth, who is wearing one in the video. “And I’ve been meaning to talk to you about it. Like, it’s cray. It’s like basically you’re a walking Ann Taylor ad. It’s crazy.”

Ouch! Luckily, Hemsworth finds it hilarious and bursts out laughing.

Hemsworth hit right back by joking, “You’re lucky you’re beautiful, because there’s nothing up here,” while pointing to his head.

The two volley back and forth several minutes before they realize it’s practically impossible to criticize perfection.
