A vampire bat returned to the cave covered with fresh blood, and all the other bats flocked around him and demanded to know where he found the blood. Reluctantly, he told them, "Come with me." they flew through the forest for a ways, then finally, he landed on a big boulder. The other bats mobbed him, demanding to know the source of the blood. Finally, he said, "You all see that big oak tree over there?" they answered, "Yes, yes" and the old bat said "I didn't."
