* "Welcome Home, Part 1" is full of moments like this, as Richie and Ralph come home from their stint in the army. One notable moment is in which Richie, Fonzie, Potsie and Ralph sit at their usual booth at Arnold's. At first there's an uncomfortable where they have nothing to say to each other. Ralph goes over to the piano and plays the opening notes of "Blueberry Hill" Richie's signature song. Richie starts singing, then Potsie and Fonzie join in and they all gather around the piano, smiling and singing the rest of the song. (This would also be the last scene in which all four characters appear together.)
** Richie jumps into frame and ''immediately'' the audience begins screaming and cheering - this goes on for minutes on end as he hugs every member of his family.
* The {{very special episode}} [[ExactlyWhatItSaysOnTheTin "Richie Almost Dies"]] is this, especially the scene with Fonzie making a deal with God ("You do this for me... And I'll owe you one.") at Richie's bedside, before [[NotSoStoic completely breaking down in tears.]] There's a meta element to it, as well: The entire reason the episode was made was that the producer had received a letter from counselors who were having trouble with abused children. The kids wouldn't express their emotions - they didn't want to cry. They all loved Fonzie for being so tough, and the counselors thought that seeing him cry might help them to realize that it was an okay thing to do. The fact that a popular tv show cared enough to respond to this sort of request in such a big way is quite touching, no matter what you might think of the episode itself.
* In "They Shoot Fonzies, Don't They?", Fonzie gets annoyed on Joanie's behalf when the head of the cheerleading squad, Jill, purposely keeps her out. Jill makes a bet with Joanie - if she and her partner can outlast her and her brother in an upcoming dance marathon, she can join. Fonzie agrees to the job. Then, the night of the dance, his motorcycle gives out and he has to push it several miles simply to get to the Cunninghams' house. In spite of his ordeal, Fonzie can't say no to Joanie; as he later explains, "This dance means so much to her." All together now...''awww.''
* Fonzie's relationship with the Cunninghams in general is this. Whether it's expressed as dramatically as in "Richie Almost Dies" or more quietly, such as with his determination to keep on his feet during a dance contest for Joanie, it really reminds us that the town's favorite cool guy has a heart under all that leather and tough talk.
* ''Hi Yo, Fonzie Away''. The gang go above and beyond to get the Lone Ranger to appear for Fonz's birthday. [[TheKnightsWhoSaySquee Fonzie's utterly starstruck reaction just clinches it]].
* Most of "A Woman Not Under The Influence" but special points go to Fonzie's reaction when Ashely agrees to a date--he catches himself leaping for joy and quickly hides it; and when they kiss at the end and [[PostKissCatatonia he's so blown away he can barely squeak out a "Bye."]]
* Joanie and Chachi announce their engagement. Howard, the father of the bride, walks up menacingly to Chachi- "Chachi, I'm going to say something, and I'm only going to say it once: I like you. Welcome to the family." and holds out his hand. Also, when they tie the knot in the Grand Finale, when Howard [[BreakingTheFourthWall thanks the audience]] for being with his family through all these years, and says "to Happy Days."
* "Guess Who's Coming to Christmas" naturally had several:
** Fonzie hands out gifts to everyone at Arnold's. When Ralph admits he doesn't have one for him, Fonzie says he's all about the giving.
** Fonzie claims that he has big family plans, but Richie discovers he lied and is spending Christmas all alone. The Cunninghams feel bad for him (even Howard, who wanted a family only Christmas). Fonzie's too proud to admit he lied or take charity, so Richie and Howard convince him to come over to help with the decorations. When Fonzie later tries to leave, Marion puts her foot down and says he's staying.
--->"Y'know, Mrs. C, my mother used to talk to me that way. She was the only one I let get away with it... until you."
** Fonzie later admits to Howard that he knows he was lying about his plans. Howard says that it was Richie who found out and made this happen.
** An edited version of the episode containing new book ends exists. In this version, it's several seasons later and Al is dragging his feet over going to the Cunninghams' for Christmas. He's got nowhere else to go, but he'd feel he'd just be out of place there. Fonzie tells him this story and expresses his gratitude for the Cunninghams giving him a memorable Christmas.
