I'm not quite sure what it is, just that it came to my mind this morning. And it's just meant in fun.

A Piratey Limerick
There once was a Captain named Jack,
Whose crew finally went out of wack;
So the grabbed Jack and his steel sword,
Threw them both overboard,
And he got stuck on an island – alack!
