From YouTube:

My cousins used to play this odd little game; they were about five and three years old at the time. The older one would pick up the remote control to the TV, point it at her sister, and say "Turn you off", she'd obligingly fall to the ground and play dead. Then the remote changed hands, they'd change places, and the game would begin all over again. It was carried out with the solemn gravity of an execution by firing squad.

This short is a grown-up version of the same game, played with a grown-up weapon...
