The boss walks in, there’s someone on the phone for you:

• Phone: “Hi, I’m the leader person behind that book/television/film franchise you complain about online and gee-whiz, you’re right! We want you to run things from here on out.”
• You: “Do I get supreme retcon powers?”
• Phone: “Of course! We’ll even retroactively edit in your changes!”

Huh, that was easy. What are you changing?
