The giant looked at the fisherman and said, "Speak to me more politely or I'll kill you." "Why will you kill me?" asked the fisherman. "I've just freed you. Have you forgotten that?" "No," answered the giant, "But that'll not stop me from killing you." "Now, tell me how you will like to be killed," said the giant. The fisherman said, "I don't believe you were inside the vase. Before killing me, please show me how you were in that vase."
