The Evolution Of Laughter [VIDEO]

Hilarious!  Yes, it may sound ironic to say this video on "The Evolution of Laughter" is funny, but it truly is!  Not in the usual way, but in sort of a contagious way.  Each of our laughs is so different, and our laughter changes from the time we are born through the years as we age.  It all becomes so evident in this video which I am sure will leave you with a smile.
