I found the video in which the cupid shuffle is found. However, I don't have 20+ posts, so I cannot post a link/image.
It can be found on nfl.com. Click videos. Click by team--go to Miami Dolphins. Under that, click Ronnie Brown. And the video is "Ronnie Brown Highlight, WK 05 vs. Chargers." The celebration between RB and VC is found towards the middle of the clip.
If a .gif can be made from the dance, I would be very, very grateful.
Take care fellas.
