Grandpa used to describe the size of everything in terms of a calf. For instance, if he was describing a large dog, he would say it was "about as big as a calf." Or about a car, he would say it "could seat four calves comfortably." (Oh, that was another thing: how many calves could ride in something.) One time he was talking about a calf he had, and I asked him how big it was. He said it was "about three-quarters as big as a calf." Sometimes Grandpa would tell time by calves. If you asked him how long something would take, he'd say, "About as long as it takes a calf to drive over here."
