The Mad Hatter/Playing With

Basic Trope: A crazy character is aware of and acnkowledges their insanity.
 * Straight: Alice is crazy and mentions this fact.
 * Exaggerated: Alice mentions her insanity in literally every sentence.
 * Justified: Alice has a mental disorder that renders her able to understand that she's not quite right.
 * Inverted: Alice reminds people that she is the sane one in a cast full crazy people.
 * Subverted: Alice says that she's crazy, but it turns out she's not really crazy.
 * Double Subverted: It turns out that she actually is crazy and continues to say that she is.
 * Parodied: Lots of Alice in Wonderland jokes pop up in the work, all directed at Alice and her insanity.
 * Deconstructed: Alice has severe mental psychological problems that she is aware of but can't fix, leading to a slow breakdown causing pain to her and the people around her.
 * Reconstructed: Alice finds a medication that takes away the worst problems that her madness causes. She still has a few quirks, but nothing major, and she continues to (mostly jokingly) refer to herself as insane.
 * Zig Zagged: We can never tell if Alice is really insane or not.
 * Averted: Alice is crazy, but she doesn't recognize it.
 * Enforced: ???
 * Lampshaded: "Let's face it. I'm just crazy."
 * Invoked: ???
 * Exploited: ???
 * Defied: Alice refuses to believe that she's crazy. Or, she knows she's crazy, but she refuses to talk or think about it.
 * Discussed: "I thought crazy people weren't supposed to know they were crazy. How come Alice does?"
 * Conversed: "I thought crazy people weren't supposed to know they were crazy. How come all the fictional loonies do?"

Yes! I know I'm crazy, but if you go back to The Mad Hatter, you won't be disappointed! Trust me!
