"Ahh-! You have a hook for a hand and your name is Captain Hook! Is that just a coincidence or is it because of your hand?" It had to be coincidence, right?

It is a bold claim, and one that causes Luffy to grin to his fullest as he releases the fellow Captain's hand.

"What kind of Captain are ya', Uncle Hook? Are you a Marine or are you a pirate?"
