I think it's safe to say that if I had been one of the lucky passengers on this subway car I would have done any or all of the following:
(A) Pissed my pants
(C) Giggled maniacally
(D) Mouthed along with the words
(E) Shoved Princess Leia out of the way
Also worth noting - when I was little I used to think that Darth Vader told Leia she was part of a "Revel of Lions" (see: "You are part of the Rebel Alliance and a traitor!).
