Can I just pre empt this video by saying flashmobs, at the best of times and inexplicably, make me cry. No, wait, that's an understatement. Flashmobs make me laugh, cry and clap simultaneously like some demented bi polar seal.
Then I saw this. Bawled. My. Eyes. Out. Smiled. My. Head. Off.
Enjoy! And remember, I claim no responsibility for snottage. K?
