David Caruso (Horatio Caine) knew his storyline with Christina Chang (Rebecca Nevins) would work out well from the moment he first met her and she immediately grasped the cast's "secret handshake."

"A funny moment happened," Caruso told reporter Pat O'Brien on yesterday's edition of the syndicated Insider TV show. "One of the things we do around here to kind of connect is we have a secret language. And one of those things is a lot of military talk. So we refer to each other as sir and ma'am, and there's some saluting going on and all that. But I was coming out of a soundstage and Christina was signing out, and I said to her, ma'am, and she said, sir, and I was like - wow, she belongs here!"

The moment apparently worked out so well that the writers ended up using it for a scene in last week's CSI: Miami episode, "Crime Wave." Caruso said that none of the chemistry between Chang and him had to be faked for that episode. "If it's there, it's there, and there's nothing you can do to kind of produce that in a false way. And it's a beautiful mystery - it's one of the most interesting aspects of this. When somebody steps into your purview, and there's a connection automatically, that's magic."

While Caruso appeared on yesterday's The Insider, his three female colleagues in the regular CSI: Miami cast were interviewed by Entertainment Tonight. They revealed that one way in which the show has changed their lives is that the "ick factor" is much more prevalent now. "I used to view the world as far more clean than I now do," Emily Procter (Calleigh Duquesne) said. "Now it is filthy. The 10-second rule that used to apply no longer does. If something falls, I am not picking it up. The: it is a cookie, blow it off, is no longer. It's gone."

Khandi Alexander (Alexx Woods) admitted to being baffled by real-life forensic experts. "I have the utmost respect for coroners and medical examiners, but they are insane. A couple of them would eat their lunch while they're doing an autopsy. I think that's amazing, you know?"

Finally, Sofia Milos addressed an equally creepy yet much more serious aspect of the show when she talked about the physical abuse storyline in which her character Yelina Salas is involved. "Strong women - detectives, cops - are attracted to strong men," she said. "In my life that wouldn't happen, but in Yelina's life, I think it is an important story to tell. It does happen and cops won't talk about it if it happens to them. They cover it up because they are embarrassed and I think Yelina is embarrassed."

Much more from the three Miami ladies, including their thoughts on how female fans are reacting to their roles, can be found on this ET Online page, which also includes a short video interview with the three actresses. More from Caruso, meanwhile, can be found in a 3,5-minute clip on the Insider Video page.
