Sunken Treasure

Met a crazy chocolate Lab named Rocky today. His owner said that one day he was playing with a damaged tennis ball in the lake, and it sank. He looked and looked for it until he finally found it underwater, and now that's his favorite game. He's bored with balls that float. He scrabbles his paws on the bottom until he stirs up the scent of some long-sunken ball (his owner calls it "dragging the lake"), then dives for it. Watch this.
