Smiling

This morning I opened my mail box and I had something waiting for me, something to make me smile:

Interesting Facts:

This "flash mob" happened in 2012, it was created by young people from Moscow, who decided to dance to an "83 year old" "american song", written by a Russian born American-Jew, whose last name is the capital of Germany (Irving Berlin).

What the people are screaming, at the end,  is similar to what they shout at bulgarian weddings:
"горчивo, горчивo"
literally translated means bitter, but what they just want is for the Bride and Groom to kiss!
