Choreographed dances by wedding parties have pretty much been done to death over the last few years. But, over the weekend, I had the honor of being in my cousin's wedding in Philadelphia, and to spontaneously be a part of a wedding party dance that one of the wedding goers managed to catch on film. This dance was definitely not planned, or choreographed (as you'll see in the video), but we managed to have a good time with it. And, I can pretty much guarantee that we're the only wedding party that has ever danced to a Black Keys song at the reception. See what I mean after the jump.
