Sure, flash mobs can be confusing for the people who are not in on it. Sometimes, however, it's a magical surprise and you just want to dance. Watch this video about a flash mob that took place at the College of DuPage. Keep your eye on the guy on the right side of your screen wearing a gray t-shirst and glasses. He just wants to dance and dance he does, perhaps a little mystified as to why everyone else seems to know these moves.
I love people who just want a little happy in their lives.
