You know those people at karaoke who always seem to sing the wrong words, even when the lyrics are right there on the screen? Well, on Friday night’s episode of The Tonight Show, Jimmy Fallon and Chris Pratt sang incorrect lyrics completely on purpose.

In the segment, appropriately titled “Nonsense Karaoke,” Pratt begins by singing his version of “Uptown Funk” by Mark Ronson. Then Fallon takes on “Stay With Me” by Sam Smith. Finally, they perform a duet of Kelly Clarkson’s “Since U Been Gone.”

It’s all completely ridiculous, but you have to admire their commitment.
