T-Rex: One day Batman, who was the best at solving crime, faced the impossible... A CRIME HE COULDN'T SOLVE.
T-Rex: Oh snap, we're one sentence in and already there's a stunning twist!!
T-Rex: The crime was a minor one: someone had stolen a candy bar from the local convenience store. The criminal, WHOEVER THEY WERE, was careful: they wore a hoodie, left no fingerprints or DNA, quietly slipped the choco into their pocket, and left. The crime hadn't even been noticed until Batman himself reviewed the camera footage a week later as part of a different case, which itself was part of his really justified war on crime!
Utahraptor: What was the first case he was investigating?
T-Rex: A slight case... OF MURDER.
T-Rex: And as the murder was clearly a more pressing case, and as the shopkeep didn't want to press charges, Batman had neither the time, resources, nor the permission to solve the case. It was quite literally the case he couldn't solve, and that's how some snack loving rando beat Batman!
Narrator: A FEW SLEEPLESS NIGHTS LATER:
T-Rex: I CAN'T DO IT, I CAN'T LIVE A LIE!! LATER ON BATMAN CAUGHT THE CANDY BAR CRIMINAL, BATMAN DEFINITELY CAUGHT HIM
T-Rex: I'M SORRY I DOUBTED YOU, BATMAN
T-Rex: I'M SORRY ABOUT EVERYTHING
