What's your favorite 'Glee' number?

Not so easy, right? That's a question that's sure to spark a heated Gleek debate. With close to 300 performances so far in the show's three seasons, there's definitely plenty to choose from.

At a taping of the show's big diva mash-up for the 300th song, the cast and crew shared their own personal favorite numbers, ranging from 'Trouty Mouth' to Lady Gaga and every Broadway homage in between. See which numbers struck a chord with them after the jump.

Conan O'Brien's hiatus between 'The Tonight Show' and Nov. 8th's premiere of 'Conan' has left a distinctly large, tall void in television. Sure, we miss O'Brien's smart, absurdist wit. However, we are referring to programming's complete absence of red hair styled into a ridiculously high wave with a flip at the end.

The late-night host's haircut is a punchline by itself. O'Brien often flips and shakes it to tag monologue jokes. He jokingly apologized for it at the end of his infamous written statement about his future on 'The Tonight Show:' "Have a great day and, for the record, I am truly sorry about my hair; it's always been that way." (We're not sorry for it! Conan made our top TV redheads list.)

The great red hairdo has been missed. It is one of the few truly distinct cuts on television. How many actors, hosts or reality stars pop into your head when you think hair? A few for sure, but nowhere near the number 20 years ago – back in the '80s when crazy hairstyles defined a person.

As we welcome Conan back into our late night TV schedules, we also welcome him back into TV's club of distinct on-air hair.

Kelly Ripa is prepping a return to primetime with a new series, 'Port Love.'

Ripa, host of 'Live With Regis and Kelly,' and husband Mark Consuelos will co-write and executive-produce the project. Consuelos will star, with Ripa set for a recurring role. According to Deadline Hollywood, the project, a single camera workplace comedy, follows the cast and crew of a once-popular TV show who have quite a lot of backstage drama.

After being hyped to the max, did the Madonna episode of 'Glee' deliver the goods? Yes! It did! Not only were the musical numbers fun, inspired, and darn creative, but the storylines about sex, strength, confidence, independence, and individuality all blended well into the theme.

Was it Sectionals or Regionals? Is Quinn still pregnant? What's up with Will and Emma? It's been a small eternity since the last new episode of 'Glee,' and let's face it: those four long months could turn even the most die-hard Gleek's memories of the Fox hit musical into convenience store slush.

So for all those whose show choir recollections have turned a little hazy over this winter hiatus, we've provided a recap (or 'Glee'-cap, if you will) of where the show left off in its 'Sectionals' mid-season finale last December -- as well as a little taste of what's to come in the episodes ahead -- just in time for the series' return tonight at 9:28PM ET.

In anticipation of the Tuesday, April 13th premiere of Fox's musical hit 'Glee,' two of the co-creators, Brad Falchuk and Ian Brennan, met with the press via a conference call the other day. TV Squad was in on the call and you'll be thrilled with some of the big news coming up in the last nine episodes of this award-winning first season. There were some insights revealed when the cast and the other co-creator and executive producer Ryan Murphy were on 'The Oprah Winfrey Show' yesterday, but Gleeks want more, and that's what this is all about.

Among the highlights – for all you who need encouragement -- Jane Lynch does "Vogue" in the Madonna musical episode. Kristin Chenoweth was not paired up with Idina Menzel, but Kristin's episode (the third one back) is supposed to be wonderful. And if you liked Puck's performance of "Sweet Caroline," wait till you see him do a song like a member of the Rat Pack. For all the details, read on.

You may not know all their names, but if you've been watching 'Glee,' you know who they are: The kids in the Glee Club have shot to stardom right along with their new hit show.

And it's not because they've got distinctive nicknames like "Wheels," "The Asian Girl," "The Cute One" and "The Hot Guy With the Mohawk" ... or because they're all talented singers and dancers. The cast members of 'Glee' are energetic, funny and a genuine kick to be around, as we learned when they visited the AOL offices to hang out with us (jealous?) and answer fan questions.

So what did we learn about Dianna Agron, Chris Colfer, Kevin McHale, Cory Monteith, Lea Michele, Amber Riley, Mark Salling and Jenna Ushkowitz? Maybe that whenever you see Kevin frown, it's because he's trying not to crack up at a Sue Sylvester line ... or that Amber thinks her character Mercedes beats up on her brothers ... or that someone once asked the cast to autograph a baby ... or that Lea has a song in mind for a potential Rachel-Puck duet ... or that Cory plays drums for real on one 'Glee' recording.

So, tell me why you're watching Glee. Entertainment Weekly put the Fox musical/drama/comedy on it's cover this week, calling it "TV's Happiest Hour." With around 8 million people tuning in each week and iTunes sales of songs featured on the show going through the roof, there's no denying that Glee has turned into a barely contained phenomenon.

EW says it's "snarky, theatrical and totally addictive." All very true, but I watch for one reason: this show makes me happy. Nothing I've seen on TV in the past few years, much less this season, puts a grin on my face like these high school kids earnestly singing and dancing. I mean, come on. Did you see Puck's rendition of "Sweet Caroline"?
