"Water, no thank you sir. Fish make love in it"

Please watch one of my favourite scenes from Indiana Jones and the Last Crusade. Elsa Schneider (Alison Doody) is talking about the Grail's diary written by Henry Jones (Sean Connery).

Elsa Schneider: He's given them to Marcus Brody.
Henry Jones: Marcus? You didn't drag poor Marcus along, did you? He's not up to the challenge.
Walter Donovan: He sticks out like a sore thumb. We'll find him!
Indiana Jones: The hell you will! He's got a two day head start on you, which is more than he needs. Brody's got friends in every town and village from here to the Sudan. He speaks a dozen languages, knows every local custom. He'll blend in, disappear, you'll never see him again. With any luck... he's got the Grail already.
Marcus Brody: Does anyone here speak English? Or even Ancient Greek? Water, no thank you sir. Fish make love in it… (…) My reputation precedes me.

Some of you may have recognized the late Denholm Elliott, who played in The Signal-Man, the television adaptation of Charles Dickens' eponymous short story.
