It's almost time. The sixth season of "Mad Men" begins Sunday night (9 on AMC) and I know what you all want: spoilers.

You're all just dying to know about really important plot developments to "enhance" (so you say) your viewing experience on Sunday. I swear, if I've had one person ask me if Don Draper's ad agency has expanded to include a new floor in their building, I bet I've had a hundred. Well, just stop it because I'm not telling you.

Seriously, what is wrong with you, because that would totally ruin Sunday night's premiere! Which is very good, and I wouldn't say that if it wasn't true. It's two hours long and it has characters from the show! Characters who go to work and drink and smoke and sleep around (SHOOT! Now you know what's going to happen!!).

Why don't you look at some publicity photos below -- if you're sure you're not going to be thrown by the fact that Don still has hair and Joan still has both of her eyes. And don't forget, Sunday night at 9 on AMC.

When last heard from, Superchunk/Mountain Goats/Bob Mould drummer Jon Wurster was getting in touch with his inner Edward R. Murrow, reporting from the front lines of America's troubled airline industry with the same sort of deadpan flair for the absurd we've come to know and love. And now he's trying on his acting shoes, sort of. Wurster pretty much steals the show with his star turn as jerky boyfriend Denny Rock in Aimee Mann's new video (a remake of 'Til Tuesday's 1985 hit "Voices Carry"), which also features Jon Hamm as the smarmy director.

As Wurster notes in the introduction, he is "basically here to crush." And he does.

As per Matthew Weiner's instructions regarding a potential review of Sunday night's two-hour Season 5 premiere of "Mad Men" on AMC, there's not an awful lot I'm allowed to tell you.

Things I specifically can't tell you:

- I can't tell you what year Season 5 is set in, though it has already been spoiled by many outlets that "Mad Men" creator Weiner removed a Dusty Springfield song called "The Look of Love" from the episode because it was pointed out by some critics that the song was not released during the timeframe of the episode. So if you Sherlocks want to know the year badly enough, Google away. (Season 4 took place in 1965.)

AMC has released a trailer for Season 5 of "Mad Men," which returns on March 25. My first thought: HATE THE MUSIC.

"Tomorrowland" is the title of the "Mad Men" season finale, and the episode looks forward. Season 4, Episode 13 left us feeling optimistic, the way people who visited Disneyland's look into the future must have felt -- until the second half of the 1960s rocketed us into a future that wasn't as bright as we thought it would be. It was a most satisfying ending to thise great season because it makes us eager to see what happens next but filled with dread, too.

Don Draper makes one of his signature impulsive moves, trying to improve himself. Peggy Olson gets high on work. Betty Francis acts like a child. And Joan Harris takes care of herself.

Losing Lucky Strike has left Sterling Cooper Draper Pryce weak and gasping for air in Season 4, Episode 12. But, as research king Geoff Atherton says, the agency still has Don. Don proves himself again as he makes a bold move to change the agency's fortunes. Whether it works will be subject of the season finale.

Early in the episode when the agency appears to be crashing down and Don doesn't know what to do, Peggy reminds him that he always said that if you don't like what people are saying about you, change the conversation. Don, the self-made man, can't just let fate have her way with him. He has to do something.

"It's the end of the world." The word gets out that Sterling Cooper Draper Pryce has lost Lucky Strike, and everyone at the agency is shaken in Season 4, Episode 11. Don vows that things will be OK, but nobody is sure that the agency will survive.

And anyone who has been through the economic downturn of the past couple of years knows what the SCDP people are feeling when they watch as their company's fortunes take a horrible turn for the worse and they don't know whether they'll be out of a job soon. It's frightening, but oddly exhilarating, too, as Stan the pig says, "It's the last days of Rome. ... The energy is very good."

Secrets come out and secrets stay hidden in Season 4, Episode 10. Don, Roger, Lane and Pete see their worlds start to crumble. And at least three of them engage in stunning displays of spinelessness. The one who shows some backbone is most surprising.

The 1960s references are everywhere in this episode. Don gives Sally a thrill when he tells her that he'll be taking her to the Beatles' concert in Shea Stadium (Aug. 15, 1965); Lane takes guests to the Playboy Club; the Cold War and the space race are key to a client's business; women sit in a doctor's waiting room to get an illegal procedure; someone makes the casual offer of a Valium; "Hazel" is playing on a television set. Yet it is the past that makes the biggest impact in this episode.

Big fat spoilers ahead about this packed episode.
 

The women and girls take center stage in Season 4, Episode 9 of "Mad Men." They show their competence, their power, their lack of power, their confusion, their ability to leave men confused. The episode ends with a workplace tableaux that I found familiar and wistful. The episode title is "The Beautiful Girls." We get a glimpse of the political and social problems of the 1960s.

"Mad Men's" Matthew Weiner gives us another shocking, funny side show, too. Here is my warning of spoilers ahead.

Blood Dolphin (9pm, Animal Planet) - In the Solomon Islands, Ric and Lincoln investigate an allegedly reformed dolphin dealer as they continue their discussions with the natives involved in dolphin hunting.

20/20 (10pm, ABC) - "20/20" examines the 1985 murder of US Air Force wife Kathryn Eastburn and her two young daughters in Fayetteville. MSgt Timothy Hennis was convicted of the murder in 1986 but the conviction was overturned and Hennis was acquited in a second trial in 1989. Then, the emergence of DNA evidence brought the case back to military court. The show includes interviews with Eastburn's father and her surviving daughter, local journalists, and one of Hennis's lawyers.

Flashpoint (10pm, CBS) - The SRU's actions are called into question after the team responds to a shooting at a museum gala. The lead investigator focuses her probe on Parker in particular.

Haven (10pm, Syfy) - Duke helps Audrey investigate the Colorado Kid case. Also, Nathan and Audrey track a killer loose in Haven, but they find a woman at each crime scene who claims to be trying to prevent the deaths she has foreseen.

Real Time with Bill Maher (10pm, HBO) - Bill Maher returns from hiatus to resume his eighth season with guests Jon Hamm, Mark McKinnon, Martha Raddatz, Michael Moore, and Robert Reich. I love any excuse to post a picture of Jon Hamm (left).
