Bring your parent to work day - for real

I'm having trouble wrapping my head around the idea that some job applicants are including their parents in the interview/hiring process.

So, let me just say this: Sorry, Mom. I do not want to take you to work with me.

It's not because I don't love you, or because I am hiding something. I just need to be an adult and make my own mistakes and successes in this life. Also, I recognize that you also work for a living and you probably have other things in your life that require your time/energy/focus.

Am I missing the point? Is it somehow a good idea to take involve a parent this heavily in your career ( or am I a bad daughter)?
