When Timberlake paid a visit to The Tonight Show Wednesday, the hilarious duo resurrected the hilarious sketch in which they “reminisce” on their days at a New Hampshire summer camp in the ’90s, in which they stayed up late and sang their favorite radio hits.
After Timberlake, 35, reveals his Halloween costume — the late night host guessed Steve Urkel and Zack Morris from Save by the Bell before correctly answering Blossom — the duo broke out into Alanis Morissette‘s “Ironic.”
Although they agreed to “keep it down” because it was after lights out, they couldn’t help but belt out the chorus, prompting Mr. Fletcher, the camp counselor, to bust in and break up the fun.
“You two potato heads need to go to sleep!” he scolded before threatening to take away their Snack Shack privileges.
Timberlake and Fallon, 42, giggled out of character as they broke into song again.
After chasing Mr. Fletcher off with water guns, the campers decided to get some shut eye.
“Hey, Jimmy, best friends forever?” Timberlake said.
“Best friends forever,” Fallon replied to a collective “Aww” from the audience.
