The Dark Knight Rises (2012)
Ben Cornish: Trader #2
[Two traders are getting their shoes shined]
Trader #2 : You can't short the stock because Bruce Wayne goes to a party.
Trader #1 : Wayne coming back is change. Change is either good or bad. I pick bad.
Trader #2 : On what basis?
Trader #1 : I flipped a coin.
[They leave, at which point the man shining their shoes reaches into his gym bag and pulls out a submachine gun]
