So it turns out that combining all three of the Internet's most hackneyed viral go-to crutches — flash mob, lip dub, and public proposal — makes a video not only watchable, but a must-watch.

Congrats, Amy. And to you, Issac, I can only say this: Great job, but I'm still not buying a Honda CRV.

UPDATE: For once, my cynicism was misplaced, and, for once, I'm glad for it. This, it seems, is the real deal, and you can read all about it over here.
