So, on The Ellen DeGeneres Show they have a thing called a "Dance Dare". The basic idea: Sneak up around somebody when they aren't looking and boogie down, just outside their peripheral vision. If you're caught, stop dancing. Play casual. Wander away.

Which brings us to this video.

Krister Shalm is a postdoc in the Institute for Quantum Computing at the University of Waterloo, Canada. He is also a swing dancer.

A couple of weeks ago, Stephen Hawking visited the University of Waterloo and Krister took the opportunity to do a Dance Dare on the esteemed physicist. The other Ellen Dance Dares are sort of club dance-y in nature, but Krister opted for a little jazz jig more fitting his personal skill set.
