Have you ever heard of flash mob dancing? A group of dancers practice a choreographed song and storm subways, restaurants, parades, stores, etc. In a flash, they come and go! It is hysterical. Here is the funniest video I have ever seen! I aspire to be as active later in life as the gentleman with the sweatband around his head. LOL! AWESOME!! Pay attention to the shock of the patrons shopping in the store.
