Prince and Pauper/Playing With

Basic Trope: Character A and Character B, from wildly different backgrounds, swap roles.
 * Straight: People believe that working-class cafe waitress Wanda is wealthy socialite Haley and that Haley is Wanda.
 * Exaggerated: Haley and Wanda do a perfect job of pretending to be each other, even knowing things they cannot possibly know.
 * Justified: Haley and Wanda are Separated At Birth, clones, one's a doppelganger...
 * Inverted: ???
 * Subverted: Wanda has a large scar that distinguishes herself from Haley.
 * Double Subverted: Haley gives herself the same scar.
 * Parodied: Wanda and Haley look wildly different but no one seems to notice.
 * Deconstructed: Wanda has no idea how to act like Haley and is identified as an impostor quickly.
 * Reconstructed: So Haley teaches Wanda how to act like her.
 * Zig Zagged: The two switch places constantly as people try to tell them apart.
 * Averted: Wanda and Haley never consider pretending to be one another.
 * Enforced: "Our plot puts the main character in two places at once, let's give him a twin or something."
 * Lampshaded: "Should I even care which one you are?"
 * Invoked: "Hey Wanda, there is something we can do, Mark Twain wrote this one book..."
 * Exploited: Haley is getting married in London while Wanda (as Haley) is attending a stockholder's meeting in Paris.
 * Defied: Wanda and Haley intentionally distinguish themselves so they can't be misidentified.
 * Discussed: "You just know those two are going to try swapping places."
 * Conversed: "I'd love to see things from your point of view. Why don't we swap?"
