These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm: (sung in a vaudeville Scottish accent) "MacGoogles is me name/I love a swampy bog...."
Fridge Logic: Max mentions he plays the bassoon in marching band, but the bassoon isn't a marching band instrument.
Never doubt the versatility of a pit band section. Over my four years of marching band, our pit included various mallet percussion, bass guitar, electric guitar, bassoons, timpani, a drum kit, even synthesized strings (played on a keyboard) at one point...
"Funny Aneurysm" Moment: Somewhat of a literal example: The scene where Jindrake is pounced by Chad the Chimpanzee and lands face-first in food-fight residue was funny. However, its hilarity decreases somewhat with recent reports that Larry Miller, Jindrake's actor, suffered a freak head concussion.
Harsher in Hindsight: A bit of a stretch, but Megan and Robe don't take Max's going to Jenna's milkshake party instead of their going away party well. Brooke Anne Smith, the actress who played Jenna, later plays a pregnant teen who ended up being mentally tortured via cyberbullying until she committed suicide in the CSI episode Unleashed by the head cheerleader in retribution to her essentially taking the prom king nominee.
McGinty's fear of McGoogles is ironic considering he went on to voice Toad in X-Men: Evolution
Unfortunate Implications: If the character's official biographies on Facebook are of any indication, Max Keeble and Jenna (or rather, Jenna Smith, as is revealed on Facebook) are cousins, and given the love triangle subplot of the movie between Jenna, Max, and Megan... you guessedit.
