Networks don't usually schedule new episodes of main shows over Thanksgiving -- it's specials or reruns -- I think that's because they figure too much of the audience is distracted... traveling or busy and those who watch are breaking routine so its a good time to promo for different audiences. You'll notice the same thing with major network prime-time shows.
