CSI: NY, Season 6

Mac:
Maybe we should be looking for what we don't see! (realises Stella is looking confused) There's a big, giant chandelier in the middle of this tiny room with no lightswitch to turn it on! So how would you do it?

Stella:
(shines her torch on the blind) Huh!? (Mac turns around as she says this) That's an odd size and place for the only window in the room!

Mac:
(looks at it thoughtfully) I'll get Flack to get a ladder!

Stella:
(stops him as he goes to walk away) Harding wouldn't have had a ladder!

Mac:
(looks at the drawers Stella has half opened) So we use the stairs)

Stella:
(smiles as he walks towards the drawers)

Mac:
(climbs the "stairs" and pulls up the blind)

Stella:
Nothing! (Mac looks at her) It's got to be all about the window! I mean the stairs lead right to it!

Mac:
This skyscraper wasn't here in Harding's day. It's blocking the suns ray!

Stella:
(chuckles) Well we can't move the building!

Mac:
So we move the sun!
