Justin Timberlake and Jimmy Fallon Sing Third Eye Blind: Video

December 17, 2014 11:20 AM EST

On Tuesday’s episode of The Tonight Show, Jimmy Fallon and Justin Timberlake made really, really great use of their acting and singing skills.

In a sketch about summer camp, Fallon and JT play a pair of brace-faced pubescent boys who can’t fall asleep (as they ate too many Pop Rocks, obviously), so they stay up late talking about crushes and their changing bodies and other pubescent boy things. Eventually, the conversation turns to music, and they launch into a beautiful rendition of Third Eye Blind’s 1998 hit, “Jumper.”

Despite getting scolded several times, they’re just so overcome with emotion that they can’t stop singing. It’s beautiful.

Also, make sure to note how many times they break character. It manages to make the sketch even funnier.
