ABC won with Dancing with the Stars (4.8), Romantically Challenged (2.9), Castle (2.6). Romantically Challenged didn't do too bad, except that the episode was so terrible that many people will stop watching. At the same time, Castle was hurt without the huge lead-in. Good move ABC!!
CBS was second with How I Met Your Mother (3.2), Rules of Engagement (3.0), repeats of Two and a Half Men (3.8), The Big Bang Theory (4.1), and a new episode of CSI: Miami (3.2).
Fox was third with House (4.1) and 24 (2.8).
NBC was a distant last with a repeat of Chuck (0.9), Trauma (1.3), and a repeat of Law & Order (1.2).
