Much like Monday, a lot of regular programs are not airing tonight. In case you're curious...
NBC is entirely in reruns; there are no new episodes of My Name Is Earl, Kath and Kim, The Office, 30 Rock or ER. Of course, don't forget about the all new Office following the Super Bowl on Sunday! Check your local listings as times will vary.
FOX is all new, though there is no new Bones. Instead there is a special episode of American Idol (the final auditions round - if you find that exciting) and the season premiere of Hell's Kitchen.
CBS has no new Criminal Minds, however CSI and Eleventh Hour are both new.
ABC has no new Ugly Betty or Grey's Anatomy, though Private Practice is new.
The CW does have all new episodes tonight of both Smallville and Supernatural.
