Friday Video: 2010 Detroit Auto Show Flash Mob. In Formalwear.

We're starting to lose patience with flash mobs. What was once an edgy, socially deviant gesture has devolved into an outlet for extroverted Michael Jackson fans and self-professed marketing "gurus". That said, we're willing to give a pass to this clip from the NAIAS Black Tie Charity Preview last Friday, since it seems like it was done for no reason other than to get the party started. And besides, who doesn't like watching wealthy, well-dressed tipplers try out their Beyoncé moves? Added bonus: check out the staffer at :30 who totally gets suckered (or maybe he's part of the act).
