On Thursday's Late Night With Jimmy Fallon, the "Suit & Tie" singer joined the program's host in a skit that showed the two having a bit of trouble sleeping one evening at summer camp...in 1983.
After deciding not to tell ghost stories or sneak into the girls' cabin to steal their underpants ("Ew, no way, cootie central!"), Fallon suggests they sing that tune they heard on the radio earlier that day.
"Oh, you mean 'Africa' by Toto," Timberlake says. "I love that song. But let's try and keep it down. It's after lights out."
Starting off quietly and then slowly raising the volume, they start dueting, only to be stopped by their camp counselor.
But once the coast is clear (or so they think), the retainer-wearing Timberlake and Fallon can't resist the urge to belt it out again. And again.
Toto would be proud.
