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.
Base Breaker: Nicholas, the British camper, especially at the end of the Apache Relay, with a remark to the Camp MVP competitor that "You Americans have no sense of history."
Hilarious in Hindsight: The shot of the kid with the marshmallow creme facepaint having chocolate thrown at his mouth ends looking strangely like a Juggalo, who are known for having similar facepaint schemes (but not with chocolate and marshmallow creme).
Moral Event Horizon: Tony was a complete dickbag the whole movie, but planning to make a bunch of out-of-shape kids climb a massive rock face barehanded, something even the most physically fit child at that age would have trouble with, would endanger their lives. Really, you can't blame the kids for locking him up after that.
Narm: The kid who says "I think they cheatin'" is easily the worst actor in the film and his entire bit in the film clearly shows that he's not an actor by trade.
Gerry's letter to his grandmother begins "Somebody once said War Is Hell, but they'd never been to fat camp." This was before Tony completely lost his mind and turned into a psychopath, at that point all that had been done was to confiscate their hidden stores of food and remove some of the recreational facilities.
Strawman Has a Point: As completely insane as Tony was, he did kinda have a point that the camp was totally ineffectual at reducing the campers' weight and needed a lot of change.
Pat also pointed that out after they got rid of Tony and found a happy medium between not helping them lose weight at all and the nightmare that was Tony Perkis.
