Two old guys and their nurse were sitting on the lawn of the nursing home enjoying the afternoon, when a little bird flew over and dropped a load on the bald head of one of the old guys. The nurse got all flustered and said, "Don’t go anywhere, I’ll run in and get some toilet paper." The two looked at each other and one of them said, "Are we crazy or is she crazy? By the time she gets back with the toilet paper, that bird will be a half a mile away."
