Fashion Designer Melissa Coker did a short film where she asked strangers to kiss for the first time.  The video's gone viral, with over 47 million views as I type this.  The results of this social experiment were surprising, and at least in one case, lasted past filming.  Coker said that the two women actually left the shoot together and spent the day together in the park.  They also hung out at a later event.

Aww...

In case you didn't see it, here's the video.
