It's a scientific fact. It's irrefutable. You cannot deny that 20 seconds of awkward Robert Downey Jr. groovin' hard will not make you smile.

We don't know much more than this: RDJ was filmed during a photo shoot for the cover of an upcoming issue of Fortune Magazine. He has some serious moves. He also sometimes looks like he's confused about what is going on. Sometimes it's best not to ask questions and just enjoy a video, you know?

Either way, next time we throw a dance party in the studio here, Robert, you're totally invited.
