New York Comic-Con's Just Dance 3 stage was always filled with an interesting mix of cosplayers, but these are my favorite: A dozen assassins from Ubisoft's Assassin's Creed line dancing to Sugarhill Gang's Jump On It with the help of Ubisoft's other major hit... Just Dance.
It's a tad long, but you should probably skip over to three minutes in to see the special guest appearance.
