If you came across a man dancing alone in a crowded train station, you would probably think that he lost his mind. Yet if you watched a small group dancing together in the same station, you might sit and watch their entertaining performance before going about your day.
If you saw this giant flash mob, however, in all their choreographed glory, you would definitely consider making a later train. Their impromptu performance is just too good to pass up!
This flash mob took pretty much everyone by surprise and, boy, was it worth it! Seeing those smiles is exactly why they did this in the first place!
