They been toying with this idea for some time, but now they are doing it. “CSI” and “Two and a Half Men” are switching writing staffs. TVGuide has:

As we previously reported, the writers of Two and a Half Men and CSI are switching teams for an episode of each others’ series to air this May. Well, for the funnymen’s CSI installment, it appears they’re sticking with their original plan and killing off their old boss, Cybill Shepherd!

This is an interesting gimmick, that sounds a little familiar (haven’t shows traded writers before?). I’m not a watcher of Men, but of course will watch the CSI-written episode. So the gimmick is working for me. It could be interesting.

Update: Katey Sagal has been cast as “Cybil”.
