Deliberate mistake: The mirror that made Rocky's face look normal should've made his mom's face look different, but her face stayed the same.
Rocky Dennis: What's his problem, Ma?
Rusty Dennis: Nothing. He's just another asshole. You let that negative dreck in and it'll put ya away. You can be a chickenshit and die or be a mensch and keep makin' yourself well.
Trivia: Rocky wasn't buried in a cemetery as shown in the end. His body was donated to science.
Question: When Rocky kisses Dianne, why is it a New Years dance if they are at summer camp?
Answer: It appears to be a party at camp. Lots of camps have special themed parties especially before the camp is over.
