Here are some of their funny exchanges from Dead Man's Chest:
Pintel: You know you can't read.
Ragetti: It's the Bible, you get credit for trying.
and it continues.....
Ragetti: [studies his upside-down Bible intently, then looks up] Well, I say it was Divine Providence what escaped us from jail.
Pintel: And *I* say it was me bein' clever. [turns to the dog with the keys]
Pintel: Ain't that right, Poochie?
Ragetti: Well, how'd you know it weren't Divine Providence what inspired you to *be* clever?
