Nuance aside, whether you’re playing yourself or a wink-wink persona, the law of cameo syllogism goes as follows: if you spend a certain amount of time playing yourself, you are no longer yourself but playing a version of yourself—a stereotype of you. Add a bonus layer if you are playing a stereotype of you in a fictional scene in which all the fictional characters are outraged by the possibility that the fictional (or fictional fictional) characters in a fictional book published by a real publishing house might be based on the actual real fictional selves they’re playing.
