The guys played younger versions of themselves who were at summer camp together and stayed up all night chatting.
While playing Truth or Dare, Justin is asked if he has a crush on anyone and her says Kimmy Gibbler from Full House. LOL!
Justin and Jimmy also can’t stop singing a Third Eye Blind song and get interrupted by a camp counselor.
Watch the hilarious skit below!
