Joker: ...so that's how I became a super villain with a massive clown army!
Palpatine: Super villain? I wouldn't go that far.
Beetlejuice: Yeah! I don't think any of that was real, bub!
Joker: What?
Skeletor: Yes! I think you made it all up!
Joker: Are you calling me an unreliable narrator?
Skeletor: Yes!
Joker: I'm insulted! Why would you say a thing like that? I was invited on TV, I shot the host and nobody stopped me, even though I just confessed to murder! That started a riot, which caused Thomas Wayne, who may or may not be my biological father, to also get shot in the alley out back! Why does that sound so unbelievable?
Skeletor: Because you are delusional!
Shredder: Because your girlfriend wasn't real!
Megatron: Because you didn't have any master plan!
Cobra commander: Yeah! That's not a super villain! That's just super dark and depressing!
