WATCH: Ploome Flash Mob at Walnut Street Lululemon Store

The students and teachers from the NoLibs Pilates studio brought some holiday cheer to Lulu shoppers last week.

I know these things have been going on for years now, but I just can’t help it: I still love a good flash mob—especially ones during the holidays.

If you were doing some shopping along Walnut Street on Friday evening, you may have been lucky enough to see this festive little flash mob live and in color. It was organized by Ploome Pilates studio in Northern Liberties, whose teachers and a handful of students descended on the Walnut Street Lululemon store to shake their thangs to Mariah Carey’s “All I Want for Christmas Is You.” Classic.

Owner Christina Stoltz told me the group tried to spread the love down the street by reprising the dance in the Apple store, but employees there were having none of it. I mean, I guess it makes sense with all those computers and iPods around, but sheesh. Bah humbug.

So they took their show on the road (literally) and performed their dance a second time in front of the Apple store in the middle of Walnut Street, which just so happened to be closed to traffic due to repairs from a water main break. Christmas miracle? I think so.

Check out the video below from their debut performance at Lululemon.
