Actor Chris Hemsworth made an appearance on The Tonight Show Starring Jimmy Fallon earlier this week and gave us another reason to love his Avengers: Endgame character, ‘Fat Thor.’

In the video above, Hemsworth tells Fallon about how he was once sitting in his trailer on the Endgame set, attempting to get into character, when he grabbed a guitar and started playing Johnny Cash’s ‘Hurt.’

Thankfully, Hemsworth recorded the performance, which might be one of the funniest behind-the-scenes Endgame clips we’ll see.

Hemsworth stars in Men In Black: International, which is in theaters now.
