The thing [Stu Redman] remembered most from [Watership Down] was a phrase: “going tharn,” or just “tharn.” He understood it at once, because he had seen plenty of tharn animals, and run down a few on the highway. An animal which had gone tharn would crouch in the middle of the road, its ears flattened, watching as a car rushed toward it, unable to move from the certain oncoming death. A deer could be driven tharn simply by shining a flashlight in its eyes. Loud music would do it to a raccoon, and constant tapping on its cage would do it to a parrot.
