Watch Justin Timberlake And Jimmy Fallon Go Back To Camp As Nerdy BFFs

I will understaaaaaaaaaaand.

You can always count on something hilarious when friends Justin Timberlake and Jimmy Fallon get together. The longtime pals -- known for previous sketches like "Hashtag" and "The History of Rap" on "The Tonight Show" -- teamed up again Tuesday night to bring back their "Camp Winnipesaukee" bit.

In short shorts and knee socks, the two guys reverted back to teen boys trying to fall asleep at summer camp, but there's one song that's keeping them awake. Justin and Jimmy reminded us that Third Eye Blind's "Jumper" exists when they revived the '90s hit in perfect harmony in their cabin beds. Unfortunately, their camp counselor didn't like all the noise and took away their snack privileges. But the best part is when the counseler tells Justin and Jimmy about his "weed-eating" incident.
