[the boys manipulate T-Rex's voicebox to amplify their call for help:]
Bill: Right, here we go. Help, please help us! We are trapped - repeat, trapped! - inside a prehistoric monster. Billions and billions of years old. Miles below ground. If you can't send help, at least send us a good ventriloquist.
[peering into the hole Graeme has just plunged into]
Tim: Oi, Graeme? You were right.... Good grief, I can't see the bottom!
Bill: I can't see *any* of him.
Bill: If you can't move, who is going down there?
Tim: [falsetto] You are.
Tim: Yes, you are. We're doing this according to the book. Listen.
Tim: "Rule Number One: Don't do it. Rule Number Two: If you're silly enough to try, one man should remain secured on the surface. He is known as the Anchor Man."
Tim: Right. "The second man will go down the hole. He is known as the Reckless Loony."
