I too am capable of waffling to an interviewer. My favourite "took down production" story is a segue into why, when your interns ask you to look over the command they're about to run against the prod environment because they're not 100% comfortable, you should do it, and a broader chat about infrastructure-as-code and review processes.

I don't think it's good practice for the interviewer to require the ability to dissemble from software engineers, though.
