Muni Diaries alerts us to this very important video: three women doing interpretive dance on a Richmond bound BART train. Fun! And fluid! But... would a little Michael Bennett now and then kill anyone? We think not. We really think not. Anyway, enjoy.

In related BART choreography news, Mission Mission has a delightful GIF of a gentleman passenger's fresh moves on a train recently. The dude performed all the way from MacArthur to the 24th Street station.
