Quote from : Pirates of the Caribbean: The Curse of the Black Pearl Movie

Mullroy: What's your purpose in Port Royal, Mr. Smith?
Murtogg: Yeah, and no lies.
Jack Sparrow: Well, then, I confess, it is my intention to commandeer one of these ships, pick up a crew in Tortuga, raid, pillage, plunder and otherwise pilfer my weasely black guts out.
Murtogg: I said no lies.
Mullroy: I think he's telling the truth.
Murtogg: If he were telling the truth, he wouldn't have told us.
Jack Sparrow: Unless, of course, he knew you wouldn't believe the truth even if he told it to you.
