There were three men…

There were three men in a boat halfway across a lake. The first man suddenly said, “I forgot my lunch. “He then got out of the boat and proceeded to walk to shore on top of the water. Later, the second man got up and said, “I forgot my fishing tackle,” and walked across the water to the shore. By this time, the third man thought to himself, “They’re not going to outsmart me. “He then said aloud, “I forgot my bait can,” and started to walk across the water…but he soon sank. The first man said to the second, “Do you suppose we should have told him were the rocks are?”
