Grissom has so many great lines!
(Ep. Pilot)
GRISSOM: You got to breathe through your ears, Gribbs.
------------------------------------------------------------
(Ep. Friends and Lovers)
GRISSOM: Let me tell you something, Humbert. You're twice the age of these kids and most of them couldn't find their a$$ with a map. You prey on innocent children concocting god-knows-what from god-knows-where selling Russian roulette in a bottle and you think we came all the way out here to bust you for "possession", you dumb punk? I'm gonna get you for murder.
---------------------------------------------------------------
(Ep. Unfriendly Skies)
GRISSOM: A, B, C, D or all of the above. Standoff with the police -- guy gets shot in the chest, runs back into his burning house inhaling smoke as he goes. The roof collapses the air conditioning unit falls on his head, he dies. What killed him?
------------------------------------------------------------
(Ep. Too Tough To Die)
GRISSOM:You're a grown man, Nick. Stop whining.
-------------------------------------------------------------
(Ep. Overload)
GRISSOM: This drill is shorted out. Do you think he "jumped" before or after he got the shock of his life?
