History Heartwarming / ItsAlwaysSunnyInPhiladelphia

* A rare find considering the [[JerkAss types of characters]] on the show: in ''The Nightman Cometh'' after the [[EveryoneCallsHimBarkeep waitress]] denied Charlie's marriage proposal, Frank was the only one who tried to comfort him. But of course it was then [[ComplimentBackfire rendered null]] by one [[CrowningMomentOfFunny line]].

* There's a legitimate one at the very, very, ''very'' end of A Very Sunny Christmas, which has [[spoiler: the gang finally all together for Christmas throwing rocks at trains, and a flashback to a young Charlie and Mac doing the same and being surprisingly sweet.]]
** And also [[spoiler: Frank's change of heart and the gang's reaction to the gifts he gets them, especially Dennis' excitement. At least, until the experience is ruined when the presents are all stolen by Frank's old business partner.]]
* While the writers try to avoid showing any thing that can be considered heart warming, the episode "Mac and Charlie: White Trash", ends with the gang cooling off with a fire hydrant, there are no jokes, no mockery, no bickering, all that is shown is a group of friends laughing and sharing a genuinely enjoyable time.
* In "The Waitress is Getting Married" even though she acted like a horrendous bitch, and humiliated the waitress in that episode, when her fiancé comes back to Dee's apartment and confesses he still is in love with her, the small silent smile on her face was just a little touching.

* Charlie's reaction in "Charlie: King of the Rats" when the gang makes him a new rat stick is amazing, as is the whole plot of the episode, with the gang coming together to give Charlie a great birthday as thanks for him doing all the dirty work at the bar. And they still give him his gifts when they find out it's not even his birthday but Frank's.
* Pretty much the whole episode of "Dee Gives Birth." From Dennis' genuine concern for Dee when she is in labor (even wanting to be in the room when she gives birth) to the looks on the Gang's face when Dee was getting rolled down the hallway, baby in hand. Set to Kate Bush no less. Later, they even laughed at one of her jokes. Who would have thought that ''IASIP'' could pull off a truly touching moment?

* In "The Gang Goes to Jersey Shore" when Charlie meets The Waitress and they spend the evening together. For a show like this, it's almost too heartwarming to believe. [[spoiler: So obviously, it's [[SubvertedTrope subverted]] when The Waitress reveals she was on ecstasy that night, and shuns Charlie the next morning. However, it's DoubleSubverted, when it's revealed Charlie honestly doesn't care that she was high, and enjoyed the night on its own merit. Aww....]]
* This troper thought it was heartwarming in the latest season finale, when one of the gang's old high school bullies tells everyone that Dennis was not really in the cool group back in high school since all he really did was go and hang out with Mac and Charlie all the time. It really shows that Dennis is friends with those two because he really likes them.

* Mac's father, [[spoiler: despite being sent back to jail because of his own son and then later having Charlie & Mac try to sabotage his parole hearing, tells Mac that no matter what his son has done to him, he will always love Mac.]]

* From way back in season 1 when Mac punches Carmen, she doesn't know she shouldn't sneak up on him, two guys react in disgust for Mac hitting a lady. Mac tries to brush it off by saying that [[UnfortunateImplications Carmen is actually a male-to-female transsexual]]. The bystanders still chase Mac down, because now they see Mac as a transphobic bully rather than a woman beater.
* [[spoiler:Subverted]] Through-out the season premiere episode, "The Gang Broke Dee", the gang seems genuinely concerned about her and supportive of her new career. [[spoiler:Until it's revealed that it's just one big plan to show her things could be worse, but only because they found her mopey "broken" behavior annoying and wanted to get back at her for joking about suicide.]]
** However, it seems like Dennis wanted Dee to be happier (and out of their hair), and thought if she did go with the plan of trying to continue her new career, she will become more depressed and kill herself. Plus, [[spoiler:he wasn't in on the plan to show her things could be worse.]]
*** [[spoiler:Double Subverted(?)]]
* "The Gang Tries Desperately to win an Award" has the gang admitting that they don't need an award to feel special. They decided that an award doesn't matter as long as they like themselves.

* PlayedWith. Although while it is quite mean-spirited and cynical in the context of the situation, in the ending of "The Gang Squashes Their Beefs", the gang end up agreeing that they shouldn't care about their relations with others because they still have each other.

*** Double [[spoiler:Subverted]]?

* From way back in season 1 when Mac punches Carmen, she doesn't know she shouldn't sneak up on him, two guys react in disgust for hitting a lady.
