We told you a while back about the plan to have the writing staffs of CSI and Two and a Half Men swap places for one episode. Looks like that plan is going forward. Two and a Half Men creator Chuck Lorre even has the plot for the CSI episode: he's going to kill Roseanne Barr or Cybill Shepherd.

OK, they won't be on the show, but Lorre's plot revolves around the killing of a "sitcom diva." Lorre worked for several years on both Roseanne and Cybill (he created the latter), and both shows were notorious for behind the scenes friction and firings and chaos. And who does Lorre want to have play the sitcom diva? Shepherd's costar Christine Baranski, who didn't exactly get along with the star of the show (or vice versa).

Now the only question is: who will the killer be? (Second question: what plot will the CSI writers come up with for Two and a Half Men?)

It may sound a little bit like a headline from The Onion, but it's actually in the works, according to CSI producer Carol Mendelsohn.

Speaking at a Banff event in Canada earlier this week, Mendelsohn said she got a call from Two and a Half Men creator Chuck Lorre, who suggested the switch. I'm not sure if it would be permanent, but it's something they could do for an episode or two. CSI will also go on location to San Francisco this season, and next season might go to London.

Maybe the Two and a Half Men writers can have Grissom sleep with a different woman every night, and maybe even hire a wisecracking kid to help with a murder investigation. He can be a prodigy who doesn't do well in school but is a genius at forensics.
