It’s the 100th – and second to last ever – episode of “Weeds” (Showtime, 10 p.m.) and the wind-up has tried to come full circle and bring back favorite former character by having Nancy Botwin and crew go back to her first suburban town, Agrestic.

It’s Jane’s wedding day on the season four finale of “Drop Dead Diva” (Lifetime, 9 p.m.).

It’s Steelers at Broncos (NBC, 8:15 p.m.) for the first Sunday Night Football game of the season. Earlier, it’s Washington at New Orleans (Fox, 1 p.m.), Patriots at Titans (CBS, 1 p.m.) and Panthers at Buccaneers (Fox, 4:25 p.m.).

When Seth Green and company get permission for their parody does it weaken the comedy? We’ll find out on the all superhero “Robot Chicken DC Comics Special” (Cartoon Network, midnight).

“Big Brother” (CBS, 8 p.m.) is getting very close to its end – just five remain for tonight’s nomination for eviction.

Jennifer Hudson sits down for an interview on “Oprah’s Next Chapter” (OWN, 9 p.m.).

The two hour exploration of the “Great Barrier Reef” (Animal Planet, 9 p.m.) promises colorful coral, fish and some marine mammals in the deep blue near Australia.

Networks blew their retrospective budgets on the 10th anniversary last year. So this year, mostly replays of the four hour “Inside 9/11” (National Geographic, 6 p.m.), and “9/11: Voices from the Air” (National Geographic, 10 p.m.).

They’re saying the 2012 MTV Video Music Awards (MTV, 10 p.m.) was the worst rated such event in years – a 50 percent drop from last year – because it was moved to Thursday. But it certainly won’t do any better as a rerun tonight.

Base consolidation is a worry on the season finale of “Army Wives” (Lifetime, 9 p.m.).

Four hours of “Once Upon a Time” (ABC, 7 p.m.) reruns is rather much, isn’t it?

It’s a double feature by director Lewis Milestone, with “A Walk in the Sun” (TCM, 8 p.m.) and “Les Miserables” (TCM, 10:15 p.m.).

With no new episodes of original series to show (how long has it been since that’s happened?) there’s a double feature of last night’s debut, “Extremely Loud & Incredibly Close” (HBO, 6:45 p.m.) and “Bridesmaids” (HBO, 9 p.m.).

Hey didn’t one of these guys speak at the Democratic National Convention last week? “A Very Harold & Kumar Christmas” (HBO2, 8 p.m.).

Vince Vaughan can be seen in both “Couple’s Retreat” (ION, 8 p.m.) and “Wedding Crashers” (Comedy Central, 6:20 p.m.),

It’s Dodgers at Giants (ESPN, 8 p.m.) in Sunday Night Baseball.
