This Star Wars surprise isn't just a flashmob -- it's an entire flash orchestra.
Germany wins 10 points.
A flashmob invaded a Copenhagen, Denmark Metro train last month, but in this case, the flashmob was the Copenhagen Philharmonic Orchestra.
They treated unsuspecting commuters to a performance of Grieg's "Peer Gynt," and creative agency Makropol captured the whole thing on video.
Right about now, a few people on that train are probably wishing they had taken their earbuds out.
