"So You Think You Can Dance" correspondent Lenni G on last night's elimination show:

Another really good group opening to the tune of "On Broadway" from choreographer, Josh Bergasse.
 
Nigel announced that next week's All-Stars will be all new except for Pasha. The "newbies" will be - Ivan, Jaime, Anya, Ade, Lauren G., Neil and Lauren F.  Can we have an Ade/Sasha team? That would so rock.
 
We also had guest entertainers including Daniil Simkin who did what I can only describe as a "mime ballet." Unique, very unique.  And then there was Blush featuring, for about 20 seconds, Snoop Dogg. "Pitchy" does not even begin to describe how far off Blush was in this number. Horrible, very extremely horrible.

"So You Think You Can Dance" blogger Lenni G on last night's show:

We have the Top 10, we have All-Star dancers and, AND we have Neil Patrick Harris (aka NPH) as a guest judge. This was mostly a great evening for everyone.
 
Marko and All-Star Chelsie were first with a Jason Gilkison samba.  As NPH said, it was an amazing way to start the show, albeit "in a sorta dirty way."  Mary called it the "real deal" and felt Jason's choreography really played to Marko's strengths.  Nigel thought it was "seamless." I thought Marko was terrific, though Chesie was probably the star of the routine.
 

Well, at least one family mystery has been solved.

Maybe casting John Lithgow as Barney's father Jerry, the suburban driving instructor starting over with a new family, is just another example of this show's proclivity for guest star cameos.

Or maybe, if we're lucky, this HIMYM story arc is an origin story for Lithgow's unforgettable Trinity killer from the "Dexter" series' fourth season.

The anti-baby crowd vowing to stop watching How I Met Your Mother as soon as Lily delivers a mini-Marshall got their wish for at least another week, but at what cost?

Marshall may have survived Monday night's fertility scare with a reassuring visit to Barney's bearded doppelganger, Dr. Stangel, but his failure to impregnate Lily had fatal consequences. How else are we to take the news at the end of the episode that Marshall's father died of a heart attack before learning that Marshall was not sterile?

Lorenzo wrote about the laugh out loud moments in last night's "How I Met Your Mother," with Neil Patrick Harris's Barney Stinson repeatedly breaking in on the "Stand By Me" duet by Wayne Brady and Ben Vereen. CBS doesn't have that clip up on their site, but they do have a clip of an unused take of the same scene. Maybe not quite as funny as the sequence that ended up in the show, but still very LOL-able. 

You know how friends and co-workers are always sending you "LOL" responses to your e-mails, text messages, and Facebook updates, even though you know they're not really laughing out loud? Because whatever you just wrote really wasn't that funny, certainly not funny enough to prompt even a giggle out of a half-drunk audience at a "Rules of Engagement" taping, but they'll toss you a courtesy LOL.

So it means something when I say "How I Met Your Mother" made me, dare I say it, laugh out loud Monday night. It's not the first episode where Barney Stinson has broken into song, but the sight of Neil Patrick Harris interrupting Wayne Brady and Ben Vereen's father-son reunion with a goofy sing-along of "Stand By Me," suggests this show may have some life left in it.

American Idol (8pm, Fox) - Neil Patrick Harris and Joe Jonas are the guest judges tonight on "American Idol." NPH could finally be the key to getting me to watch this show.

State of the Union (9pm) - The State of the Union address is airing on all major networks and all cable news networks.

Living with Ed (9pm, Planet Green) - In this episode of Ed Begley's entertaining reality show about his "super green" lifestyle, Ed visits a town in Oregon which is "off the grid" and then wants to move his family there.

Psych (10pm, USA) - "Psych" opens season four in a brand new time slot. The show has always enjoyed a Fridays at 10pm home, but with its partner "Monk" out to pasture, USA is shaking things up a bit by moving it to a presumably more ratings-friendly night of the week. The premiere episode features guest star John Cena. (First we had Stone Cold Steve Austin on "Chuck," and now Cena is on "Psych?" Well, wrestlers are by definition pretty good actors.) Tonight, Shawn thinks a soldier's suicide was really murder, and believes Juliet's mercenary brother (played by Cena) is involved. 

Also on tonight: Florida State at Duke (9pm, ESPN), Melanie Griffith guest stars on "Nip/Tuck" (10pm, FX), "Being Erica" is back (10pm, Soapnet), and "Leverage" is also on (10pm, TNT). 

A hundred episodes into "How I Met Your Mother," and we're finally granted a glimpse of the mother of Ted's future children. A glimpse of her foot, that is, as she exits stage left. (You're such a tease, Ted.)

More importantly, though, the show marked the 100-episode milestone Monday night with the cameo trifecta of Tim Gunn, Rachel Bilson and Stacey Keibler's legs, as well as Barney's song-and-dance tribute to his closet of tailored, Italian suits. 

Note to fans of "500 Days of Summer": consider Neil Patrick Harris' Broadway-style extravaganza a superior version of Joseph Gordon-Levitt's overly celebrated "I just got lucky with Zooey Deschanel" dance number in that movie. I love Hall and Oates revivals as much as the next child of the 1980s, but Harris is the true song-and-dance man. 

For too long, the Lorenzos of this world have suffered the stain inflicted on our regal name by Lorenzo "Hot or Not" Llamas. Thank you, Barney Stinson, for restoring pride and dignity to our name.

Because, as Monday night's episode of "How I Met Your Mother" shows us, nothing seals the deal on a one-night stand faster than masquerading as Lorenzo Von Matterhorn, reclusive billionaire and failed recipient of male reduction surgery.

After six episodes setting up the Barney-Robin romance, Monday's night's episode of "How I Met Your Mother" quietly dissolves the relationship. The reason? Apparently these two alpha dogs bring too much awesomeness to the table, so much that they're tired of canceling out each other's awesomeness.

As far as viable reasons to break up go, that argument ranks below more vital issues such as whether the Storm Troopers in Star Wars are robots or diaper-wearing soldiers, but hey, at least we get to see Neil Patrick Harris in a fat suit.

There is nothing metaphorical about Barney and Robin's ill-fated compatibility. As they fall into a rut, Barney's relationship gut morphs into a triple-chinned addiction to buffalo wings that leads him to choose pizza over sex. And we know that the relationship is taking a toll on Robin because of the greasy hair and her even paler, haggard appearance.
