All of these are great, but...
49: I am not to hand Ax a bag of pixie sticks, a twelve pack of Jolt cola and a bin of coffee beans "just to see what will happen".
I figure being hopped on caffeine from Starbucks contributed to his mall freakout in #5 The Predator, so this is a serious concern.
79) I am not allowed to morph into my older brother/cousin just for the purpose of dating his girlfriend.
Indeed you aren't. If sex is involved, it's rape by deception, to impersonate someone they would give consent to. For another pop culture example, this happened in Revenge of the Nerds.
I will not travel to an alternate universe to bring back the Animorphs series and dangle it in front of the Animorphs'

I thought of a similar issue with crossovers. A fandom might exist as fiction in another fandom, so it would be weird to portray that fandom as both fiction and nonfiction. For example, modern literature would be canon as a piece of fiction in a future Earth story, but it would be weird to bring that up in a crossover between the two.
