For anyone that’s ever doubted my dancing skeeelz. Or my flash mob skeeelz.

Saturday night’s wedding flashmob, organized by the bride’s sister using a YouTube to teach all 200+ attendees the dance. The entire thing was a surprise to the bride and groom, and was executed almost flawlessly. The most unexpected and hilarious part was that everyone needed started chanting the dance moves as they performed them, as had been done in the instructional video. Hence, “up up down down side side” and “sliiiiiiide pump-it pump-it”
