Today in my acting class we played a game called "Bang." And no, it's not as fun as it sounds. In "Bang," a single person stands in the middle of a circle of people and, using their "gun finger", spins around in search of a target. When found, the shooter (remember, it's only a hand gun. Literally, a gun made out of a hand) says "Bang" and fires imaginary bullets. Imaginary bullets, as it turns out, are very slow. The intended target actually has the ability to duck said imaginary bullets. We could all probably duck imaginary bullets -- if we were so inclined. You would think this was the end of the round, but don't worry, it's not. A democratic process follows the discharge of the "fire" arm. A vote is undertaken to see if the duck was fast enough for the imaginary bullets.
Regardless of the vote, this is not an effective method of execution, unless the quarry forgets to duck the bullets, which is often, as the game itself is very boring.
If it's decided the mark didn't duck in time, then they are killed, and have to move to the center of the circle to assume the role of executioner: a vengeful ghost with an imaginary gun and very slow (but not too slow) imaginary bullets.
