The idea that this video was spontaneous is why I loved it!  Finding out that the "Sugar" video from Maroon 5 is simply just another music video is disappointing.  I'm pretty sure the other 44 million viewers feel the same.  Many people recognized members of the wedding parties to be professional actors.  Ooops.

It's not like Maroon 5 were purposely trying to deceive us, as far as we know.  But the idea that it was real is no doubt how the video went viral so quickly.
