Responding with a nonsense question or statement can apparently reboot an assailants brain momentarily, and make it easier to defuse or escape. I dont remember where I read it, but apparently if someone’s trying to shoot or stab you you can scream something like “Chickens dont eat meat!” And the assailant will go " whats chickens got to do with this? Do chickens eat meat? Im pretty sure they do its just not really normal to feed them meat. But still, why are we talking about chickens?" And by then you’re uppercutting him in the balls and legging it in the other direction.
