A little girl in Spain dropped money into the hat of a man who appeared to be just another street performer, and what happened next is probably the best flash mob I have ever seen.

According to the description on YouTube, this flash mob occured on the 130th anniversary of the founding of Banco Sabadell (a city in Spain) and the creators wanted to pay homage to their city by means of the campaign "Som Sabadell" (We are Sabadell) . This is the flashmob that they arranged as a final culmination with the participation of 100 people from the Vallès Symphony Orchestra, the Lieder, Amics de l'Òpera and Coral Belles Arts choirs.
