[Inside the "war room" van, Detective Keith Frazier finally accepts a call from Dalton Russell] Dalton Russell:
I got a question for ya. You get it right, I give you more time. Keith Frazier:
And? Dalton Russell:
You know what happens if you don't. Which weighs more: all the trains that pass through Grand Central Station in a year - or the trees cut down to print all U.S. currency in circulation? Here's a hint. It's a trick question. [They both hang up] Keith Frazier:
What the hell was that? Playing games, now? Captain John Darius:
[realizing]
It's the trains. U.S. money isn't printed on paper at all. It's cotton. Mobile Command Officer Berk:
Yeah, that's, that's right. Captain John Darius:
No trees were cut down. Mobile Command Officer Rourke:
Are you sure? Captain John Darius:
Yeah. One hundred percent. Keith Frazier:
Okay. [He dials Dalton's number again. The phone rings. Dalton picks it up] Keith Frazier:
I Got it. Det. Bill Mitchell:
Wait a second, wait a second. Keith Frazier:
Call you back. [Both Frazier and Dalton hang up their phones] Det. Bill Mitchell:
It's a trap. They both weigh the same. Tell him They both weigh the same. They both weigh nothing. Keith Frazier:
They both weigh nothing or They both weigh the same? Det. Bill Mitchell:
Tell him They both weigh the same. Tell him They both weigh the same. Do it now. Keith Frazier:
They both weigh the same. Got it. [Dalton picks up the phone] Dalton Russell:
Well? Keith Frazier:
They both weigh the same. Dalton Russell:
[with evil nonchalance]
