None have ever worked on me except the ol' faithful "Hi, can I buy you a drink?" If hes tall dark and handsome, hell YES! Girls do pick up techniques too - you may not have noticed. Girls are more subtle. When I would go out with all the blokes at uni (I was the only girl), I would throw my hands up in disgust at their complete ignorance of all the girls trying to hit on them, who would eventually give up and wander off. For example: in a crowded bar, if a girl is trying to squeeze past and she thinks you are cute, she may do the "breast brush" against your back or chest as she goes by, and smile at you. Only girls can get away with this.
