Okay i guess could be used as opener but i more for doing this mid set and youre already chatting :

Say something that is incorrect and which the girl knows is wrong.
Ask them a question in which they will have to tell you that you are wrong.

Make this a simple factual error, so she can easily correct you.

Eg Youre in club /bar/shop: song comes on you say its by madonna and its actually kylie

It often helps to indicate that you have been informed incorrectly, rather than believe what you are saying is a firm fact.

When the HB corrects you, thank them and be impressed by their knowledge (but do not over-do this). This strokes their ego and positions yourself as an open person who can take criticism

Alternatively, you can debate whether the item is true and perhaps let them persuade you. By chatting some more ....

Try it out

I usually go about this in the opposit way.
If I tell the girl something like - "Did you know Mozart actually wrote this song..."
(when its Rihanna or some other stuff playing...)
She goes:
-Eh..? NO. Its not..
Me: Oh my god, its not? And here I've been walking around all my life thinking its a real classic... Thats some really impressive knowledge you have there. You could probably work at McDonalds or something..

And they allways go:
-NO... Im actually gonna be a nurse/lawyer/make-up-artist.. or whatever.

And then you go:
-Thats amazing.. Ive allways been fascinated by make-up-artist. They allways look soo hot. (Touching her shoulder slightly).
And you know stuff about Mozart too...

I never give a girl credit for anything when it comes to her answering a question.
If a give a her a compliment a will simply open by saying: You look amazing.

But I guess if its midgame your talking about it doesnt hurt to give her a sincere compliment.

Maybe I'm old fashioned, but aren't women wired to burst into flames if a man is wrong about something? My understanding is a woman wants to be led and she doesn't want to have to doubt the person leading her; that will come later.
