A vampire bat came flapping in from the night, face all covered in fresh blood, and parked himself on the roof of the cave to get some sleep.
Pretty soon all the other bats smelt the blood and began hassling him about where he got it. He told them repeatedly and angrily to go away and let him get some sleep, but they persisted until he finally gave in.
"OK, follow me", he said and flew out of the cave with hundreds of hungry bats in hot pursuit. Down through a valley they went, across a river and into a huge forest of trees.
Finally he slowed down and all the other bats excitedly milled around him, tongues hanging out for blood.
"Do you see that large oak tree over there?" he asked. "YES, YES, YES!!!!" the bats all screamed in a frenzy. "Good!" said the first bat, "Because I didn't"
