Three people walk into a pawn shop: a metafictional protagonist, an unreliable narrator, and a fourth wall breaker.
The metafictional protagonist says, "I can control my destiny and rewrite my own story!"
The unreliable narrator adds, "That's entirely true."
The fourth wall breaker looks directly at you and says, "Hey reader, what do you think? Which one of us has the most power in this joke?"
Suddenly, the pawn shop owner interrupts, "Actually, the most powerful person in this joke is the one who created us: the author. Without them, we wouldn't even exist!"
The metafictional protagonist, the unreliable narrator, and the fourth wall breaker all look at each other and then at the pawn shop owner.
The pawn shop owner smirks and says, "Just kidding, I'm actually the author. I just wanted to see your reactions."
Then i stop writing the joke.
