College football (6:30 p.m., ESPN): West Virginia at Colorado

Ugly Betty (7 p.m., Ch. 4), My Name Is Earl (7:30 p.m., Ch. 5), Grey's Anatomy (8 p.m., Ch. 4), The Office (8 p.m., Ch. 5) and ER (9:01 p.m., Ch. 5): All of these repeat their season finales from this past spring because they're all scheduled to start their new seasons next Thursday.

America's Got Talent (7 p.m., Ch. 5): Five of the 10 remaining acts are eliminated.

Smallville (7 p.m., Ch. 30): The Justice League goes searching for Clark after the fortress collapses. I keep trying to remember this show wasn't bad when it started, but it's getting harder and harder. (Season premiere)

Supernatural (8 p.m., Ch. 30): Dean returns from hell, and he has no idea who dragged him out. (Season premiere)

Flashpoint (9 p.m., Ch. 2): The unit responds to a kidnapping.

It's Always Sunny in Philadelphia (11 p.m., FX): Just when you thought this show couldn't get any less politically correct, it does. In the third season premiere, Dee and Charlie become, well, cannibals. And Mac and Dennis go hunting for, well, a human. This show is not for everyone — obviously — but it is very funny in an extremely odd way. And the reason the show has been able to get away with mining comedy from racism and drug abuse and handicaps and even abortion is that the characters approach all of these subjects with sort of a weird innocence. On paper, this show should never work. In practice, it does. (Rated TV-MA, the TV equivalent of an R-rated movie.)
