This was a fun read. I am confused by the pirate game example though.

The film opens with the Joker hiring five men to rob a mob bank: Dopey silences the alarm, Happy shoots him and drills through the vault, Grumpy shoots him and empties the cash into duffel bags, a bus runs him over, Bozo shoots the bus driver. Finally, Bozo pulls off his mask to reveal he’s the Joker. This is a classic pirate game and, just as in the theory, the Joker gets to keep almost all the cash.

This just seems like a string of betrayals that leaves one man standing at the end with all the money, not a demonstration of the pirate game equilibrium.

If you haven't seen the Dark Knight Rises, there's no real spoilers except for the last paragraph.
