Ah, "undercover" forays into the sexy, sexy world of strip clubs and swinger clubs. Where would police procedural dramas be without them? After all, trips to dark nightclubs filled with scantily-clad women help to break up the monotony of your more "standard" crimes -- you know, murder and arson and such.

On the new 'Law & Order: SVU' (Wed., 10PM ET on NBC), Detectives Stabler and Benson (Christopher Meloni and Mariska Hargitay) enter the steamy world of a swingers' club, posing as a sexy couple in order to investigate the murder of a swinger. Is this plausible? No. Is this something that real detectives ever do? Double no.

But it does give us a chance to see sultry Rose McGowan -- of 'Charmed' fame -- wearing a low-cut dress in her guest-starring role as a fellow swinger. So, that's nice.

And while Stabler locks eyes with Rose McGowan, Ms. Benson finds herself being approached by a swingin' couple with designs on her. Sometimes, these undercover missions can lead to a little more than you bargained for.
