You are a pirate captain lost at sea. You've been marooned by your mutineer crew for not taking enough supplies for the voyage. They gave you a small boat and some food and wished you well.
However the storm that happened the other day damn near capsized you and you managed keep the boat steady...you fell down exhausted from the effort. The next day...you still had your food but your boat hit a rock so you used some rope to tie the boat to it and wait. No island in sight. Then you hear a lovely song coming from behind the rock. You go and see a beautiful woman's head poking out of the water and you didn't think much until you saw her fish tail. You gasped loud enough that she heard you. Both of you lock eyes. She then looked at you seductively as if she urged you to follow her into the depths. However you knew better as a sailor.
