- The ending. Before running off to enjoy the rest of the summer with his friends, TJ shares a genuinely tender moment with Principal Prickly—climaxing with Prickly calling him "Teej", and TJ calling Prickly "Pete".
- "You did me a big favor dragging me into this, Detweiller. I didn't get into teaching for the promotions or the pension plan or so I could be at the golf course by 3 PM. I... did it because I wanted to help you kids. I'd forgotten that... until today."
- Really, Principal Prickly kinda becoming a sort of Papa Wolf towards the kids of his school, which kinda brings back the young man from the 1960s who saved his school's Recess Time from his former friend. Prickly regained his Friend to All Children card after these events reminding of him of why he became a teacher.
- This is expanded on in Taking The Fifth Grade, set after the movie. Part of the storyline results in T.J going on a room strike after several poorly thought out new school policies making life miserable for the new fifth graders, and while Prickly is more sympathetic than he would have been in the original series, his hands are tied as he's still beholdended to the school board. However, after T.J almost falls off his roof, Prickly saves him, and decides to make a stand with his student, protesting that the new directives are stupid and, ultimately, ineffective. Sure enough, having an adult faculty stand up makes the school board members admit that they had just gone along with the "expert" ideas because they were afraid of getting fired, and the new directives get overturned when everyone involved admits that they hated them the whole time.
- The last scene of the movie with T.J and friends running off to enjoy summer vacation together, with "Let The Sunshine In" playing in the background, and Prickly digging out his old peace symbol medallion and hanging it around his neck for the first time in decades.
- During the final shot of Third Street, you can see a small part of the school's paint job from the 60s still remaining
- The gang meeting with TJ in his treehouse after they all manage to sneak out of summer camp to be with him. It climaxes with them sharing their favorite summer memories together over a bowl of ice cream. Awwww...
- Equally sweet is that when Gus bursts into tears over his realization that he'll never have summer memories like the ones his friends are describing and glomps Gretchen, no one mocks him (even Spinelli is just confused about why he's crying) and even though Gretchen is obviously startled to be hugged out of the blue, she's quick to pat him on the back reassuringly.
- Not to mention, he finally DOES get to make those memories with the gang, as they rush off to what may or may not be the last summer of childhood.
- The gang singing "John Jacob Jingleheimer Schmidt" together.
- Made all the more heartwarming by the fact that TJ's older sister, Becky, was the one who taught it to them...back when she was younger, and wasn't ashamed of being seen with kids.
- Principal Prickly's speech which manages to convince TJ not to give up saving summer vacation, while revealing the fact that Prickly himself was once a carefree kid just like TJ. Doubles as a Tear Jerker.Prickly: I'll let you in on a little secret, Detweiller. Every adult you've ever known was a kid at sometime in his life. You think we don't remember summer vacation? Riding our bikes down the creek. Catching polliwogs in a jar. Camping out under the stars. Well you're wrong! Sometimes I sit there in my office, looking out at you kids in the playground and I think, "They don't know how good they got it. In a few years, they'll be grownups like me and all those good times will be memories for them, too". So go ahead. Put a whoopie-cushion in my chair. Put fake vomit on my carpet. Make fun of my "big, saggy butt". But don't ever say I don't care about summer vacation, 'cause those memories are the last part of childhood I got left.
- He says this after T.J. calls him out on how he and every adults are like Benedict, wanting to get rid of summer. Afterwards, he apologized for thinking otherwise.
- Most of the teachers' reactions to the kids leaving are pretty indifferent. Miss Grotke on the other hand, is crying. D'aww.
- TJ's friends call his older sister, Becky, to get help, but she's still mad at TJ for blackmailing her into driving him around, and yells "Give me one good reason why I should help! Just one!" Mikey, dead serious, responds with this: "Because he's your little brother, and he needs you." There's a pause, followed by Becky saying that she'll be right over.
- When T.J.'s walkie-talkie is taken away from him when he's trying to inform the gang about Bennedict's motive to get rid of summer vacation, leaving him Lost in Transmission. As soon as his end goes dead, the first one to freak out is Spinelli...who's been implied to have a crush on T.J.
- A little twisted due to coming from an unrepentant villain, but the fact that Benedict is still in love with Miss Finster, even though she has now gotten old and, to be honest, rather ugly. Of course, she still rejects him because he's still a kid-hating fascist.
- Building on that, the teachers rushing to the defence of both their students and summer vacation itself.
- During the climax, the bald guy goes after T.J. after he and Prickly had previously dumped a vat of chowder on him. But before he can get to the boy, Miss Finster stops him and gives his face the speed bag treatment, knocking him out.T.J.: Thanks, Miss Finster!
Miss Finster: [smiling] Just doing my job, Detweiler.
- Every single adult in the movie except Benedict and his goons think that getting rid of recess is a horrible idea and openly protest against it when they hear about it, dating back to Benedict's original plan in the 1960's when the parents picketed the school in protest, and got the superintendent involved, who also strongly objected to it and fired Benedict. This includes the U.S President who tossed Benedict out of his administration over his anti-recess crusade.
