Let's break down EX40SP3 like a witty detective solving a case! EX40SP3 is a peculiar acronym that stands for "Extended Specification 3 - Part 40." Now, imagine this:

---

"After the moon exploded into a giant pizza crust and rained down on the world, my friend decided to make an EX40SP3-sized pizza for the first time. It was so small, it fit on the tip of my nose, yet somehow managed to cook up enough heat to melt the walls of my kitchen oven." Edgy example sentence: "The new CEO's plan to expand EX40SP3 into space was so grandiose, it left the board in shock - 'Is this the first time a pizza has orbited Mars?'"
