As I've games girls I've reeled that they all respond immensely to the line, "I just noticed something about you." It sparks their curiosity and makes them want to know what you noticed.

And I'm trying to turn this into a hook routine but I'm not sure what I should say after this. I want to turn this interesting line into something really great.

Explanation:
Me: (After Opening and etc.) I Just noticed something about you
Her: What did you notice?

Note* I need something that can be used on any girl.
I know you can state the obvious and say something about her, like she's funny and all that, but I'd figured maybe you guys could see something I don't.

This is a line I had in mind: You seem friendly, I'd like to get to know you better" Thoughtd?

There's no one end-all, be-all line to use. But it's pretty widely held knowledge that if you tell a girl that she seems to have some personality traits, if she's warm to your approach, that she will try to fit that mold. If you tell a girl she looks friendly, and she doesn't wish you to just go away and leave her alone, that she will be a bit friendlier. If you say she looks like she knows how to go a little crazy and get the party starting, the odds that she'll buy herself a shot will rise a bit.

I'm not saying you are wrong in your idea, because you aren't necessarily off. I'm just saying try different things. Don't use one line for every girl in every situation. Don't bind yourself by turning a pretty easy to use psychological move into a script that you can't change up on the fly.
