More Music:
Sugar Pill: Ambulance LTD
Calmer: Zoot Woman (edit) Notice the last names of the couples involved in the swap party murder. They are Brady, Cunningham and Keaton. An inside joke by the writer maybe - these are all last names of families from TV shows (The Brady Bunch, Happy Days and Family Ties) where you never saw the marital relations of the parents. (edit) This episode was originally entitled "A Swing and a Miss". (edit)

Sara: Arrive as a couple, leave as a couple.
Grissom: No photos, no video.
Sara: No affairs.
Grissom: And the kids must never know. (edit) Catherine: I know that you got the memo, I'm not sure that you read it. Ecklie is being promoted to Assistant Director. They are taking applications for his supervisor spot on days. I want it. (Gil sits down and doesn't say anything) What? You want the day spot for yourself? You're worried about giving me a good A.P. score and breaking up the team? Or maybe you just think that I'm incapable of the position? Not worthy of the promotion? Is that it? I'm just always, always, always defending myself to you. I'm unbelievable. I have a daughter who is so starved for my attention, she is thumbing rides to Fremont Street to see her grandfather. The last person I want her around. I mean, not that it's much better with my mother, who sees Lindsay much more often than I do. I am missing out on my daughter's life. I have no life of my own. Would you just stop me and say something here? (Gil takes off his glasses and looks at her)
Grissom: You want the job because you're worried about Lindsay?
Catherine: That's part of it, but...
Grissom: The position calls for leadership, Catherine. You have to inspire others, solve problems, which means you have to leave your own problems at home.
Catherine: I want the job because I can do it. I'm qualified, I'm motivated and I'm ready, Gil. You know that I am.
Grissom: I do. Which is why I already sent in your A.P. I gave you 100 percent. I even put in a good word with the Director. The rest is up to you. And...I hope you get it. (Gil puts his glasses back on. Catherine's touched)
Catherine: Thank you. (Catherine stands up and walks out of the office. Gil sighs as he watches her go) (edit) Mia: Nine vibrators, five plugs and four strands of beads.
Greg: And a partridge in a pear tree. Some kids are happy playing in the sandbox, others want every toy in the store. And apparently these are dishwasher safe.
Mia: I'll swab the nooks and crannies for semen and vaginal secretions and epithelials, but don't get your hopes up.
Greg: Oh, my money's on bag number two.
Mia: Twenty-six used condoms.
Greg: Just like being back in college, right?
Mia: Sara said you didn't lose your virginity until you were twenty-two.
Greg (ignoring her): Grissom and I figured that they practiced safe sex so we checked their trash. Check them inside and out, please.
Mia: I've analyzed condoms before, Greg. Just not in bulk. (edit) Doc Robbins: Have you no poet in you?
Grissom: Beauty is truth, truth beauty. That is all you know on Earth and all you need to know ... Except cause of death. (edit) Grissom: As Lord Byron once said: "In a desert, a fountain is springing."
Brass: Well this one sprung a dead woman. (edit)

Doug Savant's appearance marks the fourth star of Desperate Housewives to appear on CSI. The previous three were Brenda Strong in Overload (season one) and Marcia Cross in Organ Grinder (season two) and Steven Culp in Dead Ringer (season four). (edit) The porn magazine that Sara finds in the desk drawer in this episode is the same magazine that Nick finds in the drawer of the monk in episode 2-17 Felonious Monk which first aired 2 1/2 years before this one. (edit) Warrick states that the graveyard shift catches about 15 to 20 cases a week. (edit) When Greg takes a sample from the pool at the Brady's, we first have a plan of him taking the sample in a labelled box and closing it. A bit later, he's still sitting on the side of the pool, and is closing a sample. Again, a little later, we see him labelling an empty box. He finally get up, showing one labelled and half full sample box and saying "Got it". (edit) When Hodges comments on Greg's spelling mistake on the water sample from the pool Greg says that's how they spell fountain in Norwegian (he spelled it funtain). In Norwegian it is actually fontene.

Response: It seems obvious, though, from Greg's reaction and his looking at the jar that he's using an excuse, probably just to annoy Hodges. (edit)

Grissom: As Lord Byron once said, 'In the desert a fountain is springing.'

This is yet another of Grissom's literary references - this time from Byron's Stanzas to Augusta, the full reference being:
In the desert a fountain is springing,
In the wide waste there is still a tree,
And a bird in the solitude singing,
Which speaks to my spirit of thee. (edit) Grissom quotes the poet John Keats' poem "Ode on a Grecian Urn" ("Beauty is truth, truth beauty") during the autopsy and then, having discovered evidence has been suspicously washed, cites John Wesley's famous maxim "Cleanliness is next to godliness". (edit)
