Justin Timberlake and Jimmy Fallon took a trip back to Camp Winnipesaukee on Wednesday’s episode of The Tonight Show Starring Jimmy Fallon, and brought the melodies of Alanis Morissette with them.

The longtime friends played camp BFFs who just couldn’t go to sleep without singing Morissette’s hit song “Ironic,” much to the consternation of their counselor.

The sketch had a distinct Saturday Night Live vibe — including Fallon and Timberlake unable to hold in their laughter.

This is the fourth time Timberlake and Fallon have done a variation on the Camp Winnipesaukee sketch. The pair previously played kids singing Third Eye Blind’s “Jumper,” Hootie and the Blowfish’s “Only Wanna Be With You,” and Africa’s “Toto.”
