See, this is why you can't totally quit SNL. Just when you think the show is beyond lame and that a guest host like Taylor Swift is sure to be weak and boring, it surprises you with goodness.

Not greatness, but solid goodness.

There were many solidly good moments in last night's show, starting with Swift's hilarious "Monologue Song," in which she took hilarious jabs at Joe Jonas and also addressed her current boyfriend Taylor Lautner (the werewolf in "Twilight") and of course, Kanye West. And speaking of "Twilight," the digital short spoof on that movie ("Firelight") which subbed Frankenstein monsters for vampires, was dead-on. I also loved Swift in the PSA about dangerous things parents do while driving. Even the very last skit, an infomercial for an album called "Bunny Business," had funny impressions of Natalie Merchant, Shakira, Adam Duritz, and Jennifer Hudson.

Tonight is the much anticipated season three finale of "Mad Men" and there are so many issues to resolve. Will Betty leave Don? If so, will she leave behind those children she can barely stand? Will Peggy and/or Pete fly the coop for Duck's shop? What about Sal -- is he coming back, or still trolling around that park? Most importantly, how do we get Joan back front and center?

Heck, we don't know. "Mad Men" is a complex show and Matthew Weiner is a crafty dude. That's why we asked "Mad Men" expert Jesse McLean. McLean is a pop culture writer and author of "The Kings of Madison Avenue: The Unofficial Guide to Mad Men."

We asked McLean for predictions and also about how he feels the show deals with issues like family and race. He told us why he thinks family life is portrayed in such a depressing light, and why Joan makes him feel good.

Check out the Q&A below.

Mad Men (10pm, AMC) - In case you've been living in a spider hole, we're here to tell you that tonight is the season 3 finale of AMC's stunning series, "Mad Men." Last week's episode, despite the JFK assassination storyline, was a teeny bit of a snoozer. But perhaps that's only because the previous week's episode, in which Don was forced to come clean to Betty about his true identity, was one of the most powerful we've seen. One major development last week, apart from confirmation that Duck is completely devoid of a soul, was Betty telling Don that she no longer loves him (Also interesting? That part where she made out with her new boyfriend in the car). What happens tonight? Your guess is as good as ours, but our guess isn't as good as this guy's. Don't miss it!

Dexter (9pm, Showtime) - Quinn's very interested in Dexter's nocturnal habits, which doesn't bode well for Quinn's future. Meanwhile, John Lithgow's creepy Trinity killer is still on the loose.

Bored to Death (9:30pm, HBO) - In the first season finale of this great new show, the Edition magazine gang -- George (Ted Danson), Jonathan (Jason Schwartzman), and Ray (Zach Galifianakis) -- prepare for a triple-header boxing match against Richard (Oliver Platt) and his GQ crew. It's not pretty. It's very funny, but it's not pretty. 

Brothers & Sisters (10pm, ABC) - Not only are we still getting to look at Gilles Marini guest starring (forever, please!) as Sarah's steamy French love interest, tonight Nora (Sally Fields) turns all cougary and begins an affair with a younger oncologist working at Kitty's hospital, played by none other than Jon Tenney (you may know him as Fritz Howard on "The Closer"). And even better, Tenney's Dr. Simon will have a recurring role on the show (but only a 4-episode story arc). Gilles Marini and Jon Tenney (not to mention Rob Lowe). Sigh. 

Wanda Sykes launched her late night show last night (Fox, 11 pm) and got down to being Wanda right away.

The show played to her strengths with a lot of stand up, giving plenty of opportunity for her in-your-face riffs, taped skits like she used to do on Chris Rock's HBO show, and most effectively, a Chelsea Lately style roundtable.

A couple of hours before "20/20" broadcast the interview of singer Rihanna by Diane Sawyer, I was involved in a three-way, sometimes loud, discussion about the Rihanna/Chris Brown incident.

The guy in the conversation, who is a good guy, basically said that it was odd that Chris Brown beat Rihanna for no reason, thus suggesting that somehow Rihanna was at fault somehow, and then said that he thought it unfair that Chris Brown was still a pariah. He feels that we (society) shouldn't hold celebrities to a higher standard, and, I guess, in real life Chris wouldn't be having it so hard.

Again, this is a good guy. And I hope he watched Rihanna's interview because she addressed all his issues.

The Wanda Sykes Show (11pm, Fox) - Tonight is the debut of Wanda Sykes' new talk show, the first late night network talk show hosted by a woman since the Joan Rivers disaster of '86. Don't expect this one to go down in flames, though. Wanda Sykes is hilarious and it's a smart move to go for Saturday nights. Wanda's show will have an open bar for her guests (which should make things really interesting), and will include sketches, a monologue, and panel discussions about current events. Using Chris Rock's old HBO show as a blueprint, Wanda says she wants her to show to be fun and wants viewers to feel like they're "hanging out at my spot with me and my friends.” Her first guests include Mary Lynn Rajskub, Daryl “Chill” Mitchell, and “Amazing Race” host Phil Keoghan. The show will air each Saturday night at 11pm on Fox.

Saturday Night Live (11:30pm, NBC) - SNL returns tonight after a couple of weeks off, and Taylor Swift is the host and musical guest. I'm expecting at least one Kanye West joke. Question is, who can play Kanye? Will they draw some crop circles on Fred Armisen's head and make him try that one too?

Evil pretty people are extra scary, probably because we like to think that things that look good are good.

That's why Rob Lowe is well cast in "Ann Rule's Too Late to Say Goodbye" (Lifetime Movie Network, channel 47, 8 tonight).

Lowe uses his borderline feminine looks as Bart Corbin, a successful dentist whose wife Jenn, as the movie opens, appears to commit suicide. Her young son finds her with a gun in one hand and divorce papers in the other.

For my money, the funniest moment in NBC's two-hour comedy block last night came during Pierce's (Chevy Chase) college rock band debut, playing keyboards and singing backup to Vaughn's woeful song of heartbreak (and moving on), "Gettin' Rid of Britta."

The lyrics are clever, and Vaughn is easy on the eyes in that sensitive musician kind of way. Rocker Vaughn won me over with lines like, "It isn't like I would ever hit her, but I would sell her to the highest bidder." But it's Chevy chiming in with "she's a no good B" and "she's a G D B" while jamming on the keyboards that had me cracking up -- and watching over and over and over again.

The second-to-last episode of a boring season has come and gone, and well, there were a lot of tears.

It'll be good to go back to New York City for the next season. L.A. never seemed like the right fit and most of the season's challenges were uninspired. This episode, however, did bring back some of our favorite things: an inspiration-in-a-museum challenge, sharp critiques from Nina and Tim, petty backbiting and, best of all, really awful clothes!

Lamest episode of "The Office" ever? It hasn't been brought to a vote by the Happiness is a Warm TV blog's high tribunal, but consider yourselves on notice, Office writers.

Your once great show has devolved into the weak link in NBC's Thursday night comedy lineup, fourth behind an inconsistent 'Community' show that would have you believe community colleges have dorms on campus for international students.

Thursday night's episode wraps up Michael's ill-fated relationship with Pam's mom.
