The two--both with impressive curly-haired wigs--can't get to sleep so they decide to stay up and have some fun, starting with Truth or Dare. "Is it weird if it's just two boys?" Timberlake asks. Of course not!

The two then have a little fun singing their favorite song, Third Eye Blind's "Jumper," even doing a little harmonizing. But since it's after lights out, they have to be quiet. Of course they can't do it. I mean, it's "Jumper"!
