[from extended version]
[looking at the elvish rope]
Frodo: We can't leave this here for someone to follow us down.
Sam: Who's going to follow us down here, Mr. Frodo?
Sam: It's a shame, really. Lady Galadriel gave me that. Real elvish rope.
Sam: Well, there's nothing for it - it's one of my knots. It won't come free in a hurry.
[tugs rope, rope falls]
Frodo: Real Elvish rope.
