After The Lonely Island stopped by The Tonight Show Starring Jimmy Fallon on Monday night to promote their new movie,Popstar: Never finish Never Stopping, the talk-show host got them to sing one of their most famous hits using only classroom instruments. Like Meghan Trainor before them, or Andy Samberg,Akiva Schaffer, and Jorma Taccone got creative with Fallon and The Roots as they sang "I'm on a Boat" while hilariously backed by kazoos, and a rubber duck,and some flippy-floppies. Watch their fantastic rendition above, and then check out all the other noted musicians Fallon has gotten to sing with classroom instruments!
