Parodied: When Mentor uses his powers he does a silly mystic dance and says silly mystic words. He says these are necessary and so Bob does them, until he faces the Big Bad and doesn't have time for silly gestures. The Big Bad is shocked he can do this. Mentor blows a refree's whistle and makes Bob sit in a penalty box.
Zig Zagged: Bob claims to have broken the rules, but is actually exploiting Loop Hole Abuse. An Obvious Rule Patch makes further expolitation impossible but Bob breaks the rules anyway. Then The Powers That Be invoke Rule Zero, which prevents it from working again. Bob says he has another method....
Averted: No one breaks the rules, or conversely, there are no rules to break.
Enforced: "What better way to shock the audience then for Bob to break the rules of magic?
Lampshaded: "Bob, you can't break the rules of the universe whenever you feel like it."
