"I know the idea of being threatened by sheep is amusing, but rams are quite large, and if they butt you onto the ground, they’ll probably keep doing it for a while."
Near to where I live an old man was killed by sheep recently. They trampled him to the ground and just kept on trampling until there was only a bloody mess left. It'd never have happened if he was young and strong, but it sounded to me as though the sheep really did want to kill him. I've heard about sheep pushing someone in a wheelchair off a clifftop, too. I'm not making any of this up!
