What is the ultimate rhetorical question?!

Question:

What is the ultimate rhetorical question?

---

I was trying to find Yahoo's Rhetorical Questions & Answers, but.....

Answers: What is the ultimate rhetorical question? Why are you talking (disbehaving, etc.)?? (A teacher to a class or parent to a child)

Or someone saying "What's your problem??"...??

Or someone say "Am I..." because they don't want to know the truth... most at least... trust me.

Or if someone's wife asks them "Do I look... in this dress?"
The best thing is to walk away... Anything you say can and will be used against you... :o) It used to be......
A wife to a husband......"what are you thinking?"

Right now it's just "What do you think?" "What?" haven't we met? i think you'll understand the nuance!! Why? answer, Why not? When someone asks, "What's wrong with him (or her)?", I always respond, "A lot!" best retorical question i heard was can i ask you question its stupid and funny cuz you already asked a question its funny...
