- Accidental Innuendo: Buck punching the clown. Get it??
- Big-Lipped Alligator Moment:
- Miles' inexplicable view of three intimidating guys through the mail slot.
- Maizy's seemingly normal teacher, who suddenly screams "BLASPHEMER!", like some sort of religious maniac, after she uses the expression "God-damn", quoting her uncle. Its a downright non-sequitir in the TV edit, which censors the words altogether.
- At one point, Buck's car does it's standard backfire as it comes to a halt at the party; in this instance and this instance alone, James Brown's signature "Wah!" can be heard.
- Ensemble Dark Horse: Miles Russell, since his scene at the mail slot was the inspiration for the Home Alone films.
- Harsher in Hindsight: Early in the film, Buck is attempting to remember the names of the kids and recollects Tia being ten years old, and is shortly chastised by Tia - although that's to be expected - when he doesn't remember Miles and Maizy's names. Later on we learn through Buck's viewing the photo album and Tia's mixed gloating and whining at Buck, largely because she's not allowed to go out, that Buck has largely been shut out of the family for years. No wonder, in that case, that he doesn't know where his brother lives or the names of the kids, who don't seem to know him at all; Buck was shut out to the point he'd never met them before.
- Retroactive Recognition:
- Unintentionally Sympathetic: Buck himself. The marketing and other characters save for Miles and Maizy almost seem to paint him as the black sheep of the family for reasons that — much like Tia's jerkassery — are never really fully explored; even the film's poster depicts the family trying to comically barricade themselves in to stop him, but Buck in the film is much more sympathetic and decent than the majority of the cast seems to see him as. The worst thing he does is dodge work... By having to come and look after his brother's kids.
- Unintentionally Unsympathetic: As detailed elsewhere, Tia has issues with her parents that are never really fully explored save for one attack on her mother for leaving her grandparents; while she'd otherwise be a stock teenager from a John Hughes movie, the lack of explanation and her overall attitude toward the much more sympathetic Buck can render her difficult to like until she and Buck finally reconcile.
- Wangst: A lot of Tia's behavior, especially towards Buck, until the end.
- What Do You Mean, It's Not for Kids?: Despite the family theme, there's some crude sexual humor (particularly the Not What It Looks Like scene with Marcie) and an Attempted Rape.
- The Woobie: Buck never does anything in the movie or in the backstory to justify the obvious contempt in which he is held by his entire family. Indeed, everything he does indicates that he is at heart an intelligent, caring man who simply acts unusual in response to being treated like a pariah.
- Moresoever, his unusual behavior consistently proves necessary to prevent the disastrous consequences of him being ignored- up to and including an attempted rape which he clearly saw coming.
- While Buck wasn't exactly living a very good lifestyle... among other things, his only income was gambling (apparently also involving fixed horse races), and nearly drove the kids to the racetrack when Tia drove off, the fact that his sister-in-law treats this like he was some sort of low-life criminal mugging people at gunpoint reflects much worse on her than it does on Buck... as does the fact that his own brother never stands up for him.
- At one point prior to Bob calling Buck, she even cites Chanice's job as being problematic in having Buck watch the kids; she sells tyres for a living.
- Tia is a Jerkass Woobie, extremely harsh and critical to everyone around her, especially Buck, but is extremely depressed, bordering on clinical.
YMMV / Uncle Buck
