Okay, just remembered a couple more of jokes that you need to watch Black Pearl before you can understand them:

• "Elizabeth! Quick, hide the rum!" Elizabeth is guilty for using several crates of rum that Jack hid to light a beacon.
• The eunuch joke. I kid you not. When Jack "inspected" Will, he made a scissors motion with his hands, and all the tribe natives went "ooooh, eunuch...." When Jack first met Will, he said, "Or, perhaps the reason why you practise three times a day is because you already found a girl, and unable to woo said strumpet. You're not a eunuch, are you?"

Go watch the movies already.
