Will: “We’re going to steal that ship?”
Captain Jack Sparrow: “Commandeer. We’re going to commandeer the ship. Nautical term.”
Barbossa: Why thank you, Jaaaaack.
Jack: You’re welcome
Barbossa: No, we named the monkey ‘Jaaaaack’
Seconded.
I really liked this one too.
Geez, Captain Jack Sparrow is just owning this list. Another favorite.
(Talking to Elizabeth) “If you would be so kind”
(She puts his hat on him) “Now if you would very kind”
(She puts his belt on him) Careful with the goods, love"
Or something to that effect.
Question: Were all these great POTC lines scripted, ore were some ad libbed? Do any of you know a way to find out on the internet?
Another from PoTC
Barbossa: Well, I’m afraid I’m disinclined to acquiesce your request. Means “no.”
Ahem.
The Merovigan’s[sic] stream of curses followed by, “Its’ like wiping your ass with silk.”
Also from the Matrix Reloaded from the Merovigan:
“Okay, you have some skill.”
Pirates of the Caribben -
“You forgot one thing… I’m captain Jack Sparrow.”
makes me wanna see it again just to hear that line.
(doesn’t look at all cool just in writing like that, but it is it is it is!)
Haha. The spelling makes this funnier. 
You could tell Geoffrey Rush was having fun with his role, though. 
Who wouldn’t? All that thar runnin’ around yellin’ “Arrrr” all the time. Right good fun.
How about this Cap’n Jack classic: “…and then they named me their chief.”
Yarr… I be have’n a hard time tell’n which thread I be in now.
Captain Jack has taken over the SDMB, it seems.
for the while, anyways…
yarrr
Your [I}friends{/I]? I could have sworn there was only one of me. God help the world if there are two of me 
I told you that you were going to LOVE that part of the movie
I saw Seabiscuit over the weekend.
Good.
Had my 8 yr old niece with me. She liked it, too.
Some memorable lines:
When walking into War Admiral’s track mates stables and seeing how posh they were, Red says, “Jesus! I wanna be a horse!”
The jockey friend guy to the owner about whether to let Red race again, “Sometimes, it’s better to break a man’s leg, than to break his heart.”
