"That Dog Is Never Going To Move"

In many old movies, prisoners are kept behind locked bars that has only one key, and that key is usually guarded by a dog.  That key (excuse the pun) to escaping prison is persuading the dog to bring the key to you.  In The Pirates of the Caribbean: Curse of the Black Pearl, trapped behind the bars in Port Royal, Jack stands by and watches the other prisoners desperately beg the dog for the key. Prisoners: "Come here, boy.  Want a nice juicy bone? Come here, boy."  Jack: "You can keep doing that forever.  That dog is never going to move."  Prisoners: "Oh, excuse us if we haven't resigned ourselves to the gallows just yet."  Once all the other prisoners are gone, Jack himself must turn to the final resort.  Jack: "Come on, doggy. It's just you and me now. It's you and old Jack. Come on. That's a boy. Good boy. Come get the bone. That's a good boy. Come on. A bit closer. A bit closer. That's it. That's it, doggy. Come on, you filthy, slimy, mangy cur. Don't do that. No, no! I didn't mean it!"  Maybe that wasn't the smartest move...

As it turns out, the dog does move.  In the next movie, The Pirates of the Caribbean: Dead Man's Chest, it's Pintel and Ragetti, the two goofy crew members of the Pearl, who are trapped in the Porty Royal prison.  They however, are much more successful with coaxing the keys from the dog.  Pintel:  "Well, I say it was Divine Providence what escaped us from jail."  Ragetti: "And I say it was me being clever.  Ain't that right, Pooch?"  The two sail to the island where the Black Pearl is stranded.  Confused and not finding anyone, they start to prepare the boat to set sail.  Suddenly, Gibbs, Will, and the other crew members run for the ship.  They hop on board the Pearl but find that there is a dilemma.  WHERE'S JACK?  Just in the nick of time, Jack runs onto the shore, chased by the cannibal islanders who plan to eat their god, Jack.  Jack quickly climbs on board, leaving the cannibals completely confused.  That's when they see the dog, who has been left on shore by the crew.  The islanders have found their new chief/god/dinner.  

It seems as though we'll never see this dear dog again after he is left behind, but as it turns out, he's unbeatable!  In The Pirates of the Caribbean: At World's End, the nine pirate lords run into some disagreements about the pirate king and declaring war.  To settle these disputes, the Keeper of the Code, Captain Edward Teague (aka Jack's father) is called out with his gigantic book of the Pirata Codex.  Of course, this book is highly guarded and requires a key to open.  And who better a guard of keys than the good old prison dog from Port Royal?  Pintel and Ragetti, of course, are completely astonished to find this dog alive.  Ragetti: "That can't be."  Pintel: "How?"  Teague: "Sea turtles, mate."  Now where does that sound familiar?
