Sign No.1 that Stephen Colbert is a genius: If you're going to throw and epic dance party, you should definitely do it to the song of the summer, Daft Punk's 'Get Lucky'. How can anyone not move when that song comes on? They're emotionless and a terrible friend, that's how.
Sign No.2: How do you make an epic dance party extra mind-blowingly fantabulous? Invite (and force) some of the industry's biggest stars, like Hugh Laurie, Jeff Bridges, Matt Damon and Jimmy Fallon to join you.
All of that should be enough to entice you to watch this super rad video, but if not, just know that it IS guaranteed to make you smile and why wouldn't you want that? Huh?
Also, let us point out that Bridges' staircase dancing is sorta making us think he had a past life as a (exotic) dancer and as for Jimmy Fallon, well, the bastard stole our dance moves.
