P.S.I. Luv U, on CBS
IMDb; TV.com; TV Tango; Wikipedia

This lasted for just 13 episodes, in 1991-92. I don't remember it well, but I do remember finding it quirky and amusing. There was this cop played by Greg Evigan (who I may have still remembered at the time from "BJ and the Bear," a show I used to watch a long time ago). He was involved in a sting operation, working with a con woman played by Connie Sellecca. They were trying to take down a mafia guy, but it didn't work out, so they had to go into witness protection. They posed as a married couple named Cody and Dani Powell, and were given jobs at Palm Security and Investigations, in Palm Springs (hence the "P.S.I." of the title). So... the premise was kind of redonkulous, these two people who didn't really like each other much, having to pretend to be married and do private investigating work together. But whatever, I really liked it and it'd be cool to see it again sometime. Which I probably never will. (And if I did, I might like it less than I did originally. Or not.)
