You know what makes us happy? OK, yes, pie and champagne and presents, but also flash mobs. Come on -- who didn't start grinning like an idiot during the flash mob scene in "Modern Family" the other night?

A real flash mob took place recently in a food court in a shopping mall near Niagra Falls when a 100 member choir began singing "Hallelujah." We smiled, we laughed, we got chills. And then, we decided to share with you. Enjoy!
