Justin Timberlake Goes Back to Camp with Jimmy Fallon & They Sing Some Classics! (Video)

Justin Timberlake is putting his comedic chops to work for a hilarious new sketch on The Tonight Show Starring Jimmy Fallon!

The 36-year-old entertainer joined his longtime friend Jimmy to go back to camp in the “Camp Winnipesaukee” sketch, which also featured cameos from Keegan-Michael Key as a camp counselor and Billy Crystal as another camper.

After playing a game of two truths and a lie, Justin and Jimmy started singing “What’s Up” by 4 Non Blondes, but they got in trouble by their counselor (Key) for making too much noise. They couldn’t help signing the song again, and got in trouble yet again.

At one point, Justin had to hide his face under the blanket because he was laughing so hard and then joked that he’s having an allergy problem.

When the guys finally decided to go to sleep, Billy showed up as a camper from another camp and they all started singing Gloria Estefan‘s “Rhythm Is Gonna Get You.”
