Don't fuck with a good thing

It's Monday again, and normally there would be several hours of great comedies (How I Met Your Mother, Rules of Engagement, Two and a Half Men, and the Big Bang Theory) on CBS.
Having originally created (probably by accident) this great bloc of funny stuff, CBS, of course, couldn't leave well enough alone. Now that each of them is a success in its own right, they are dragging them (doubtless kicking and screaming) to other nights, in a vain hope of moving the magic (and the audience) with them.
Rules of Engagment is already scheduled to move to Wednesday, with How I Met Your Mother to follow it, according to CBS. This, after having already moved Julia Louis-Dreyfus' The New Adventures of Old Christine to Wednesdays. (The new Monday, apparently.)
Bad network behavior, but then (as usual) they didn't ask Rico...
