(Grissom rushes into the room. He seems excited)
Grissom (smiling): You have to see the birthday present I got for your daughter.
Sara (walks in): What's the rule? How long do I have to be here before I start kicking in for gifts?
Catherine: When the spirit moves you, Sara. So, in your case, I guess, never. (Grissom opens the box and shows Catherine the chem set that he's holding in his hand)
Grissom: I got one of these chem labs when I was six. I almost blew up the whole house. (he chuckles)
Catherine: I hope you can return it 'cause, uh, Lindsey doesn't want a party. Grissom: Yeah, what kid doesn't want a party?
Catherine: My kid.
Nick: Hey, Catherine what time's your little girl coming by?
Catherine: She isn't.
Nick (holds up his gift): Yeah, but I got her a chem set.
Sara: You keep that; might learn something.
Nick: Stop flirting with me. Cath, really, when's the party?
Catherine (exasperated): What do I have to do --- put it on the bulletin board? There is no party. My daughter doesn't want a party. Is everybody clear on that? (everyone's pager goes off, they all leave, as Grissom leaves he places his chem set on Nick's)
Grissom: We'll play with these later. (leaves, and Nick laughs)
