About 10 years ago, we were at a holiday party. I was standing next to the fireplace, talking to a lady, who had picked up what appeared to be a piece of driftwood from the mantle, and was holding it, marvelling at its texture. It was cylindrical, about 2 dfeet long, about 6" thick.. Our host joined us, and the lady asked him what it was..."The pertrified penis of a male walrus" he replied..
