What's On Tonight: That Show With Summer Roberts Where She's Not Playing Summer Roberts

Hart of Dixie (The CW, 8 p.m.) — Season premiere. Speaking on behalf of Danger/sane people: Summer > Anna.

How I Met Your Mother (CBS, 8 p.m.) — “Lily comes to a realization.” That she’s been awful since season 3?

Monday Night Football (ESPN, 8:30 p.m.) — It’s the 2-2 Jets vs. 1-3 Falcons, so check how your fantasy teams are doing on your phone while you’re catching up with Sunday shows tonight. Baseball scores, too.

Mom (CBS, 9:30 p.m.) — If you’re not watching this, do so, but only until the first act break. It’s a fascinating disaster: every episode packs in approximately three dozen plots, and not even Anna Faris, Allison Janney, and Badger from Breaking Bad can save Boner Joke #83 from Chuck Lorre’s trapper keeper full of them.

The Blacklist (NBC, 10 p.m.) — I’m 97% sure James Spader is legally insane.

LATE NIGHT GUESTS: Tom Hanks on Letterman; Drew Barrymore, D.L. Hughley, and the Avett Brothers on Leno; the cast of Modern Family on Kimmel; Zooey Deschanel on Ferguson; Dylan McDermott and Paul McCartney on Fallon; Kathleen Sebelius on Stewart; and James Spithill on Colbert.
