An Answer

The Grim Reaper waved a bony hand, and suddenly the endless black desert was replaced by an endless corridor of mirrors.

"Here, you will remain, until you find the answer, and only then-"

"73."

I didn't think a skull could look deadpan, but it managed it.

"73?"

"Yeah, that's the answer."

"I don't think so."

"Well what's the question?"

"It's more metaphysical than-"

"Metaphysical questions are easy, any answer works for them. 73. Final answer."

The Grim Reaper sighed, then a small portal opened in its hand.

"73?"

There was a pause.

"I suppose if you count... Yeah, that'll do."
