Just another funny night! Watch the video below in case you missed it... 

via eonline.com 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.
