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.
Alternate Character Interpretation: As an example, imagine Harry Potter as a god-like figure among men, who constantly has to restrain his own power and is frequently drunk before noon. Every character is treated as such, some to a greater extent than others.
Big Lipped Alligator Moment: Harry occasionally gets bored and starts to daydream of fantastic things. This usually happens when there's an action scene that doesn't really lend itself to relevant commentary. Examples include Harry daydreaming about climbing a giant wedding cake shaped like Dumbledore's hat, and conquering the United States with a telescope while befriending sasquatch and yeti and marrying a Native American shaman woman.
Epileptic Trees: Both daydream narrations happen during broomstick scenes, perhaps to play off of Harry's natural talent at flying; he's so good on a broom that he literally doesn't have to pay any attention whatsoever to what he's doing and can still succeed. In contrast, Harry must pay attention during the Cribbage match because there are more variables than usual: Queerman's broom-shaking curse, the other players on the field, and the Snitch itself's own advanced flight skills.
Hilarious in Hindsight: A couple of the lines, such as "Ron likes Twizzlers" and Dumbledore being referred to as beautiful, seem more hilarious if you're familiar with another Harry Potter parody.
His descriptions of Harmony are also similar to the musical's treatment of Hermione. He even uses the phrase "Harry FREAKIN Potter!" at one point.
Memetic Badass: Harry and Ronnie "The Bear" Weasel get nothing short of glorious sweet nothings spoken of their grandeur throughout the story.
