Kurt sabotaging his own audition to spare his father the harassment and their subsequent conversation. "I'm just saying I love you more than I love being a star."

Sue's storyline in "Wheels": taking on Becky as a Cheerio and her motivation behind it.

From 1x13, "Sectionals": Will running to catch Emma before she left, then kissing her, all against the backdrop of the Glee club singing "My Life Would Suck Without You".

"Keep Holding On", mainly the subtle things like Quinn's little moments with Artie and Kurt.

Finn's mom agreeing to take in Quinn after her parents find out about her pregnancy and throw her out.

The entire Glee club singing "Lean on Me" to Finn and Quinn at the end of Episode 10.

• This becomes even more heartwarming when you notice the small moments, such as Quinn and Finn's reactions and Brittany hugging Rachel.
  • Even more so when you realise those reactions were real, the actors had no idea what the others were going to perform.

Brittany's friendship with Becky in "Wheels"

Mr. Hummel: (to Kurt) You are your mother, y'know? She was always the strong one.

Kurt's whole storyline in Episode 4.

In "Sectionals", Rachel supports Mercedes to sing the Ballad, but what makes really hearwarming is Rachel face when Mercedes is singing, she looks genuinely happy and proud of her friend, showing a huge Character Development since her Diva days.

Quinn sincerely telling Mercedes that she (Mercedes) is beautiful, and staying with her at the nurses office until her mom comes to get her. Later, Quinn being the first one to get up when Mercedes is singing "Beautiful".

In "Funk", after New Directions learn about the brutal humiliation Rachel suffered at the hands of Vocal Adrenaline, the boys are incredibly furious and don’t hesitate to go after the members of Vocal Adrenaline in her defense. Also worthy of noticing is not only that Kurt; someone who was lukewarm at best to Rachel; was one of most furious and enraged, snarling that “Rachel was one of them and only they could humiliate her” and on a secondary note, while Will’s emotion to this was subtle his sheer rage in his voice when he calls Jesse on Rachel’s cellphone is also worthy of noticing

• Kind of a Crowning Moment of Nakama too.

Will hugging Finn when he breaks down after finding out Quinn is pregnant.

Subtle momement but when Puck and the other two football players help carry Artie + wheelchair out of the auditorium as the Glee club all leave in outrage in "Throwdown". Keep in mind, these are the same guys that locked Artie into a Port-a-Potty in the pilot.

• It should be note, they are likely to have been doing this everytime that Artie has to go to the auditorium, so this is just one example of them helping Artie out.

The New Directions kids singing "To Sir, With Love" to Will, complete with telling Will how much he means to them and some of them being in tears.

• That scene was so touching that Sue had tears in her eyes.

As of episode 7, Rachel's morning exercise motivation isn't "win a Grammy" but "Sectionals," showing her Character Development into more of a team player that no longer sees glee club as just a tool to become popular.

Everyone joining Artie in a wheelchair dance (the even dress like him in a simple button-down shirt, slacks, suspenders and wheelchair gloves) in "Wheels."

• This is the first time the entire club has worn an entirely identical outfit without any personal touches or variations.

Ho Yay aside, pretty much every scene between Kurt and Finn in "Ballads."

From the Lady Gaga episode where Kurt's father confronts Finn about his homophobia.

Sue, both voting New Directions as best glee club at Regionals, and allowing Glee Club to exist for another year.

• And when Sue stood up for New Directions and, by proxy, other underprivileged students, when she said that those kids shouldn't be discredited just because they aren't as fortunate as Vocal Adrenaline.

It's a small moment, but Quinn's genuine smile when she's paired with Artie in "Ballads"

Finn's baby blanket speech.

Rachel and Shelby's duet of "I Dreamed A Dream" after Shelby is revealed to be Rachel's mother. Also a Crowning Music Of Awesome.

Artie and Tina's date in "Wheels."

In the episode 13, Santanna admits that the Glee Club "Is the best part of my day" even if she also said that she would deny it later.

Kurt reconciling with his father at the end of "Laryngitis."

The whole club standing beside Kurt and Finn to face down a couple of bullies, decked out in full Lady Gaga and Kiss costumes (except Tina who gloriously went back to her goth style), then laughing and reveling in being "freaks".

Pretty much all of the season 1 finale; Journey

More of a outside the show moment, but still heartwarming. This video that Mark Salling made for the Glee Cast and Crew http://www.youtube.com/watch?v=hQAKfSbjf6s

Mercedes singing "Beautiful" at the latest pep rally to protest her being ordered by Sue to lose weight.

• notice that this is a C Mo H for the Cherios who did this against Sue's plans

Anytime Sue talks to her sister. She actually SEEMS HUMAN!

Puck singing "Sweet Caroline" to Rachel in front of the whole Glee Club.

Finn singing "I'll Stand By You" to the baby's sonogram video.

The "Imagine" number from 1x11 (Hairography). After the club tried to use the titular technique to be as flashy as they can, in comes a Glee club from a deaf school, and as they recite John Lennon's song and repeating after the lyrics in sign language, the Mc Kinley Glee Club joins in, finally realizing that, sometimes, less is more. I think that may just have been the most touching thing I've seen on television, at least as far as I can remember right now.

Will's Manly Tears of happiness at the thought of having a baby.

Will selling his car to buy a minivan for his family, showing that despite some of the problems she can cause him, and for all of her flaws, he actually does love Terri and is serious about starting a family with her.

"My life would suck without you."

Will giving the lead in Les Mis to Bryan Ryan in order to save the Glee Club from losing its school funding.

Puck singing Beth to Quinn and his unborn daughter

All the Artie/Tina scenes in "Dream On," some more Tear Jerker than Heartwarming.

The group's 'covert jam session' in Throwdown, just for how happy and casual they look.

Rachel: "Break a leg" Finn: "...I love you."

"We have another year!" The reaction is just as much the cast celebrating as the characters they play.

Burt: Room looks great, son. (Holds Kurt's hand while they both tear up.)

'Somewhere Over the Rainbow' in the season finale. Pretty much sums up the entire show.

When Finn puts his father's old helmet on Kurt during 1x10.

Every single shot of Will's face while Emma has him on the phone during the "New Directions" songs at Sectionals.

Quinn reaching over and touching Artie's shoulder when he's singing 'Dream a little dream of me' in 1x19

The scene in "Funk" where Will apologizes to Sue/convinces her to take charge of her Cheerios again.

Will: Your girls are losing it without you out there. You say you don't have love in your life?

Sue: My girls don't love me. They fear me.

Will: But you love them.

Kurt telling his father he's gay and his father telling him he's known for years and accepts it.

Will helping Artie tie his shoes in "Wheels."

Will and Emma's first date in Episode 14

April and Will singing "One Less Bell to Answer/A House Is Not a Home" together and holding hands.

Finn and Kurt bonding over the deaths of Finn's father and Kurt's mother.

In "Hairography" after Quinn decides once more to give her child to the Sheusters she hugs Will and you get the idea that she's doing it not just because she thinks he'll be a good father to her child but because she sees him as the father she wishes she'd had.

Finn singing a verse of "A House is not a Home" to his father's ashes

[[duplicate]]

Though "To Sir, With Love" has already been added, Finns speech deserves to be it's own CMOH. "I didn't have a father, someone I could look up to... Model myself after. Someone who could really show me what it meant to be a man." He's talking about Mr.Schuester.
