Justin Timberlake was in New York with his tour so he decided to stop by The Tonight Show for a visit.

But not just any visit. He and Jimmy Fallon reprised their roles as teenage campers! This time their jam of choice is Third Eye Blind's 'Jumper' from 1997.

Watch the hilarity ensue.

I love when they break character and try to hide their laughing. That is my favorite.

'I would understaaaaaaaaaand!'
