Have you seen the Bar Scene in the movie Hitch

When he walked up to a girl and all the guys were hitting on her, and Hitch( WILL SMITH) gave her a hundred bucks, and told her the drinks he wanted as if he were talking to a waitress and then walked away.

This can be done in almost any situations, you can walk up to a girl give her ten bucks or something and walk away, as you walk away she will follow you and ask you why did you gave her the money and she is ready to be sarge and she will found funny the way you catch her attention.

Make sure she is not a homeless cause she could keep you money.

People are complaining about being caught using stuff from Mystery's show...how many people do you think have seen Hitch? Now think to yourself, how many of these people are GIRLS? Back to the drawing board in my opinion.

- Memento

Well, Where you live United Kingdom and in the United States this things are commom and popular, but there's a lot of places where this things are brand new and only a few ones like me know about them, I mean latin america, but anyway thanks for the advice.

you can definitely pull it off but if you get caught never give credit to mystery or the book unless you can tell they'll think it's cool

It would work best with a wingman though
here's a sample scenario after she follows you wondering about the money with the added aspect of being called out

HB: Why did you give me 10 bucks?
BOB: to get some drinks for us
HB: I thought you were talking to the bartender
BOB: my my aren't we naive
HB: I'm not naive..
BOB: (raises eyebrow)
HB: Wait that's lame, you got that from that show the pickup artist
BOB: what's that? my friend and I watched Hitch and he bet me I couldn't pull it off. But the one condition was I could only do it once and it couldn't just be any random person. We've been here a few hours already
HB: So why me?
BOB: Well, you're different then anybody else here (make it a tad sarcastic)
HB: different? (generally slightly insulted)
BOB: Look around.. so you're saying that you're just as lame as all these other girls. is that what you're saying?

at this point they're not going to argue and they'll have been talking enough with you to have put their guard down at this point.

Remember, every statement you make and question you ask is fixed to elicit a specific response or answer from them so there shouldn't be any surprises or curve balls thrown at you if done properly
