Let's see I meet a model on the street. Below is an imagined dialogue.
I approach her, say, "You have a nice figure."
Model: Thank you.
Me: I don't know if your brain matches your figure?
Model: Huh?
Me: I don't know if the intelligence of your brain is proportional to your body?
Model: That's none of your business.
Me: ....(Don't know what to say)

If it was you, how would you respond after model said "It's none of your business"?

This conversation is already crap and it is unlikely you can recover. You have done two things wrong.

1. Never compliment an obviously attractive woman on her appearance.

2. You have offended her by questioning her intelligence. Women shut you down once you offend them.

Now for your hypothetical situation, I would say "What I meant was, I have heard that beautiful women's brains work differently, that they are less open to new experiences and adventurous. Do you think that's true?"

She will probably say "No." and then you can say "Well, would you go base jumping with me?" And she will say "No. That is way too crazy." Then you can tease her about not being adventurous and say "Fine, I was hoping to do something really exciting, but I guess I'll have to settle for going out for a drink with you instead."

BAM. Get her number easily after that and enjoy that model.

What if she says, "Well, I may try it someday, but not with you." How will you respond?

Then you failed.

OK. Suppose I failed, should I pull away, feeling humiliated?
