It was a game show throwback on last night's "Tonight Show," with guests Nick Jonas, Usher, and Jeff Daniels teaming up with Jimmy Fallon for an impromptu round of the retro game called Pyramid.

Although there's action aplenty in the video below -- including Daniels attempting to twerk, and Usher sporting the world's most fabulous horse-themed sweatshirt -- the real takeaway from their competition is that Nick Jonas has some unforgivably enormous holes in his cultural knowledge base. Charged with identifying classic gangster films, Nick wasn't able to identify a single one. Do yourself a favor, dude: Take the day off, and watch "The Godfather."
