Share The Photo And Watch What Happens: Does Anything Happen?

Have you seen the posts on Facebook asking you to 'share' a photo or status and "watch what happens"?  This is the one I saw on my local newsfeed this morning:

Being leery (not wanting to catch/spread a virus), I have not clicked/shared the photo/status.  Have you?  Did anything happen?  I am curious!!
