CSI: Crime Scene Investigation2000

Greg Sanders:
[Grissom and Catherine walk into Greg's lab to see him rocking out to blaring rock and roll music] I could have been a rock star.

Gil Grissom:
There's still time, Greg. Tell us about the foreign substance we found in the vic's wound track.

Greg Sanders:
Uh, well, I like to rub it all over a lady's body. Even better... I, uh... like it when she rubs it all over me. And it's also used as a stool softner.

Catherine Willows:
It's also the only open lead in our case. Spit it out, Greg.

Greg Sanders:
Mineral oil.

Gil Grissom:
Possibly used as a preservative to prevent rusting of high-carbon steel.

Catherine Willows:
Like the blades of knives.

Greg Sanders:
Old knives. New ones are made from stainless steel. Yeah, I'm like a sponge. I just absorb information.

Gil Grissom:
I thought that was my line.

Greg Sanders:
Yeah, and I absorbed it.

Catherine Willows:
Okay, so... knives, screwdrivers, ice pick, letter opener. We're looking for a weapon with a splash of mineral oil. I'll grab the ALS.

Greg Sanders:
An ALS. For mineral oil?

Gil Grissom:
Mineral oil fluoresces at 525 nanometers when filtered through a kv590. A little more absorbing... a little less rock and roll.
