They're already pre-empting
I loathe the networks during February!
Although the next episode, "Tennis Any Crumb?" was scheduled to air on Feb 9, ABC's website now lists it as pushed back to Feb 16 (where possible finale "Maybe I'm Tony Randall" was scheduled to air). Undoubtedly, this is because those a-holes at ABC played it last night (against high-rated "Bones," "Supernatural" and loved-but-rating-deprived "Scrubs") and it failed to pull in the same ratings it gets when aired with "Dancing with the Stars."
"Grey's Anatomy" (don't get me started on my hatred for that show) is now scheduled to air in a 90 minute block (???) on the 9th.
