Fionn, the servant, cooked the fish but burned his fingers while turning the fish. As he sucked his thumb to alleviate the pain, all the knowledge of the world passed onto him. From then on, Fionn just had to bite his finger to access knowledge. He went on to become the leader of the ” Fianna” the famed Heroes of Ireland
