For some reason I always loved those movie scenes
When the villain is holding someone at gunpoint or is holding people hostage and either the person being held at gunpoint or the hostage negotiator (depending on which of the two scenarios it is) is talking to the gunman as if they're best friends. As soon as the gunman is distracted by something, the person being held up/the negotiator lunges for the gunman's weapon. If it fails, he then starts pleading with the gunman, "Don't shoot! You win! That was stupid of me to do that! You win! :( "
