S.F. sure loves a flash mob -- especially one involving Michael Jackson, on the King of Pop's birthday (yesterday). And even if we find the flash-mob thing a little yawn-inducing at this point, we are jaded and you don't have to listen to us. We'll try to be more encouraging. Such joy! Such presumed spontaneity! It's a wonder to behold! Anyway, we especially like the girl at the 0:28 mark in the pink tank top who decides to join in the fun, even though she clearly did not have her marching orders or know any of the choreography. That, friends, is a big flash-mob no-no. [Mission Local]
