Stumbled across this video on Holy Kaw, and it just makes me smile! Talk about holiday spirit. This is what happens when the holiday season and jazz hands come together. :-)
It seems to be from an NYC-based YouTube duo called The Yahs Initiative.
The funny coincidence is that when I watched the group's other holiday video, it turns out that my high school classmate is featured in it! Look for the random Asian dude.
Hope this gives you the dancing feeling.
