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 smelt the blood and began hassling him about where he got it. He told them to leave him alone and let him get some sleep but they persisted until finally he gave in.OK, OK, do you see that tree out there? he asked, pointing through the mouth of the cave.Yes, yes, yes! the bats all screamed in a frenzy.Good, said the first bat, Because I didnt!
