History Heartwarming / TheBigBangTheory

* The birth of Howard and Bernadette's daughter, Halley, and their choice of Godparent: Raj.

* "The Inspiration Deprivation": Mrs. Davis informs Amy and Sheldon that if they win the Nobel in Physics, Amy will become the fourth woman in history to recieve that honor, and that would make Amy a role model for young girls who want to pursue science. After Amy eventually suffers a breakdown from the pressure of possibly losing the Nobel Prize and being a disappointment to women everywhere, Sheldon cradles her and sings "Soft Kitty" to help her calm down.

* [[https://www.youtube.com/watch?v=RJZQsyuFAOA The closing segment of the season finale... the whole thing]]. In the lead up to Howard and Bernadette getting married there had been some tension in the group, especially between Leonard and Penny over a horribly misjudged marriage proposal, but watching Howard's space launch Penny muses in awe that she didn't think he was actually going to go into space and Sheldon says with a tinge of jealousy "[[Franchise/StarTrek Boldly go]], Howard Wolowitz." Bernadette and Raj both talk about how scared they are for Howard's safety and hold hands watching it happen. Penny reaches to hold Leonard's hand, which noticeably catches him off guard. But the biggest surprise is Sheldon, the poster boy for HatesBeingTouched, reaching out to grab hold of Amy's hand. Amy's reaction says it all.

* A deleted scene reveals that Stephen Hawking sent Sheldon and Amy a wedding gift shortly before he died. It's a pocketwatch for Sheldon, engraved with a note from Hawking, saying he's glad Sheldon married Amy. [[ShipperOnDeck "It's about time."]] The message is signed, "Love, Stephen." Leonard, and to a lesser extent Sheldon and Amy, are all teary-eyed after hearing one last message from Hawking.

* After working with Mike Massimino for Howard's trip into space, the cast returned the favor with a [[https://www.youtube.com/watch?v=a_wRR6H1h3Q skype call to a friend of his actually on the International Space Station]], Joe Acaba. They started off the call by introducing him to "an astronaut's wife," Melissa Rauch still dressed as Bernadette and slowly the entire cast and crew came into view. Joe Acaba was very grateful and returned the favor by showing a real-time image of Earth through a window.

* At Comic-Con 2016 the writers revealed that they had cast Katey Sagal as Penny's Mom, which is a fun CastingGag from ''Series/EightSimpleRules'' where she was Kaley's mother. When they were fielding ideas of who to cast, they weren't sure Katey would be interested but when talking to her she was ecstatic, saying "I am always ready to play Kaley's Mom."

** Even better, Sheldon slips it into their contract without any intent to bring it up (Penny is the one who notices it when they're reviewing the document). He didn't even mention this act of serious kindness and personal growth, and was apparently content to do it

*** In another episode, Raj ends up confessing to breaking his girlfriend Emily's dresser when snooping around her apartment. At first, she gives him some [[WhatTheHellHero harsh words]], but shortly after she forgives him, pointing out that their first fight was bound to happen. In a show filled with {{Unsympathetic Comedy Protagonist}}’s, this was a surprising twist.

** Sheldon and Leonard's interactions with one another in this episode, even [[TastesLikeDiabetes though Howard would find it annoying]].
* When Howard hears of his mother dying, Sheldon wants to say something. The others, afraid that he'll say something inappropiate, try to stop him, but Howard lets him speak. Sheldon then says the most appropiate, and heartfelt, thing he's probably ever said.

** Albeit she should've been arrested for it, Bernadette threatening the airport employee to get the lost ashes of Mrs. Wolowitz in her and Howard's hands is this after hearing how guilty he felt about not spending enough time before she shortly died. It's nice to see despite how they bicker, she still loves him.

* The Chuck Lorre VanityPlate's can sometimes be dark and/or crude but the one at the end at the end of "Hesitation Ramification" [[http://www.chucklorre.com/index-bbt.php?p=436 bucks the trend in a nice way]]. The episode dealt with Penny getting a small break with a three-line bit in an episode of ''Series/{{NCIS}}'' and she gets humiliated when her role and scene were cut out entirely. In a subplot with Raj and Stuart they were to talk with a nameless girl played by Lexie Contursi for a three-line bit that also ended up getting cut for time. Lorre notes the irony and expressed regret on that part of the business, and the really nice thing is he didn't want her or her friends/family to worry that the part was cut because of the quality of her performance, the exact thing Penny was angsting over.

* In "The Expedition Approximation," [[https://www.youtube.com/watch?v=5xcQqry_aQM Sheldon and Rajesh are in a steam tunnel practicing for dark matter testing in abandoned mines]]. While down there, Sheldon confesses that switching to a new field of study at thirty was scary for him. To comfort him, Raj tells him about how he was scared when he moved to America, comparing his plight to the Voyager probe floating out in space long after his mission was over. Unfortunately, [[MomentKiller the mood was ruined]] when Sheldon saw rats climbing on top of Raj and beat a hasty retreat without bothering to tell him why.

* When Penny wins a Wine Tasting experience, Bernadette and Sheldon opt to stay behind because Sheldon dislikes wine and Bernadette is pregnant. Sheldon then creates a Dungeons and Dragons style game to make Bernadette feel better about her pregnancy, which includes the fact that [[MrSeahorse men are the ones to get pregnant in that world]], and that Bernadette can drink, eat sushi, and her feet and ankles have never looked smaller. She really seems to enjoy it, and he tells her that she can come play with him anytime.

* Penny actively supporting Leonard novel before she discovers the female charecter is based on her, she's very encouraging and supportive of him and tenderly kisses his cheek.

* " The Seperation Oscillation" has several heartwarming moments:

** Also the episode serves as sweet form of closure for Leonard and Penny after their breakup in Season Three. Leonard finally realised that Penny is with him not out of pity or because he wore her down but because she sincerely loves him.

-->'''Leonard''': Well, turns out she really knows how to help a guy loosen up and have a good time. Although, truth be told, my groin is a little worse for wear.
-->[Sheldon hits Leonard in the shoulder with a Judo chop]

* " The Romance Recalibration" has Leonard and Penny get into a huge fight over the state of there relationship, eventually with Sheldon and Amy help they decide to create a Relationship Agreement to resolve there issues.
** What makes this more heartwarming is the fact that Leonard and Penny are actively trying to save there marriage and decide to work on restoring there spark, unlike Season Three where there arguments resulted in there breakup.

** The episode has many moments of genuine freindship between Amy and Leonard who bond over there love of science and Leonard provides support and encouragement to Amy over how good her relationship with Sheldon is going and her fear that marriage may change it.

* In episode 10, Sheldon is devastated when a theory he was working on appears to be disproven. He stumbles across an old video of his dad coaching a football game, admitting that things look bad but encouraging his players to still give it their best effort. Not only does this inspire Sheldon to return to work ("It's only halftime, there's a lot more physics left to play"), but it also makes him realize that the perspective he'd always had of his father was incomplete, which sparks an epiphany about his theory. Given how little Sheldon and his father understood each other while he was alive, It's incredibly sweet that it's his dad who finally helps him get over things.

-->'''Sheldon''': The true hero doesn't seek adulation, he fights for what is right simply because it's his nature...I was wrong. Minstrels will write songs about ''you''.
-->''There once was a brave lad named Leonard, fi fi fiddle dee dee. He faced a fearsome giant, when Raj just wanted to pee...''

--> '''Leonard:''' You know, Sheldon really ''doesn't care'' when you pay him back. It's one of the few idiosyncrasies that doesn't make you want to... you know... kill him.

-->'''Ramona''': Dr. Cooper, I have to tell you, your friends are holding you back.
-->'''Sheldon''': I prefer to think of it as I'm pulling them forward.

* There's this brief exchange in "The Alien Parasite Hypothesis," after [[https://www.youtube.com/watch?v=Nyp9mCVVycM Sheldon makes an insult to Penny]].
