I was wondering about that too, but I always thought I misheard it, because I never understand what Jacksays because he slurs his words, but anyhow, in the first movie-
* Jack cuts off liz's corset*
Guard- Never would have thought of that
Jack- Does he say Then clearly you've never been to Singapore, or clearly you've never been to sea before? I never knew which one, bc Jack slur his words... probably from too much rum
in the story--then they made me...it's a reference back to a monty python skit, please don't ask which one. I read this somewhere--
I discovered on my own though Jack's rather rauchy statement when at Tia Dalma's place the black spot is discovered. He says "I just want you all to know I can still see as well as I ever have".
