Watch Chris Hemsworth Sing Johnny Cash As 'Fat Thor'

Appearing on 'The Tonight Show Starring Jimmy Fallon', Chris Hemsworth showed the host a hilarious video from the set of 'Avengers: Endgame'.

Following the lift of the super-tight spoiler ban for the hugely popular flick, a flood of epic clips and pics have been released by the stars of 'Avengers: Endgame'. None of them, however, can top 'fat Thor' covering one of the world's saddest tunes -- Johnny Cash's 'Hurt'.

When host Fallon questioned Hemsworth as to whether he had any "contraband" content from his time on set, the actor certainly did not disappoint.

"This is a world first. No one has seen this before,” Hemsworth told Fallon. “I didn’t know if I was ever going to show it.”

According to the Aussie star, the video came as a result of him hanging out in his trailer between takes, where he thought to himself, “‘What would Thor want to hear right now?’" in reference to the character's loss of friends and family over the course of the films in the franchise.

And if you're wondering why the previously chiselled, hammer-wielding, god-like Thor suddenly looks like a poor man's Big Lebowski, it's because he ate his feelings of grief after the semi-apocalypse brought about by Thanos.

“It’s the saddest song in the world," Hemsworth told Fallon of Cash's track, which was recorded in 2002 just before the singer's death. "And I’m a terrible singer and a terrible guitarist," he added.

Well, sure, he's no Johnny Cash, but we think he goes alright.
