A vampire bat came flapping in from the night covered in fresh blood and parked himself on the roof of the cave to get some sleep.
Pretty soon all the other bats smelled the blood and began hassling him about where he got it. He told them to knock it off and let him get some sleep but they persisted in hassling him to no end until finally he gave in.
"OK!" he said with exasperation, "Follow me." and he flew out of the cave with hundreds of bats following close behind him. Down through the valley they went, across the river and into the deep forest. Finally he slowed down and all the other bats excitedly gathered around him.
"Do you see that tree over there?" he asked.
"Yes, yes, yes!" the bats all screamed in a frenzy.
"Good," said the first bat, "Because I DIDN'T!"
