"I realized that I don’t think I’ve ever actually been asked the question in a real job interview. I know that if an interviewer did ask me, my opinion of him would drop considerably."

I feel like this person has not been through enough job interviews. This question is standard fare, so you better be prepared for it.

Also, it doesn't really matter if your opinion of them drops--they're interviewing you. Just take on the questions as they come and knock em out the box.
