I would sail to Treasure Island and get all the treasure. I would be a greedy pirate so I wouldn't share my treasure. But I will give my first mate some.
I might train my sister to become the next dread pirate Roberts and every night I would say to her, "Good job. Great work. I'll most likely kill you in the morning."
I would throw captain Black Stash's hand to the crocodile.
That's the kind of pirate I would be.
