Dancer: Hi. Do you need a hand with that?
Grissom: Uh... no, thanks. I'll be fine.
Dancer: Are you a doctor?
Grissom: Of sorts. I'm just, um... looking around.
Dancer: See anything you like?
Grissom: Yes. I do. (he picks up a music box, the dancer walks away)
Grissom: Catherine? (he opens the box and it play music) Tchaikovsky's "Waltz of the Flowers". (he looks underneath the music box and grins)
Catherine: What? Why are you smiling?
Grissom: It's playing our song.
