funny pick up lines:
One of the easiest and most effective ways is the familiar approach: start talking to them, like you've already know them. Just start in the middle, like you'd go on from where you left off the last time you two met or just start with anything new, just as if you were talking to an old acquaintance of yours:) Skip all opening-lines (99.9% of them suck and girls hate them) and introductions (she's gonna be offering her name and phone number soon anyway, you just need to construct the opportunity for her:). It is very important not to convey the image that you are hitting on her, at least not while initiating contact. Being friendly (and not drooling over her), being confident (and not sweating, trembling and stuttering) and being humorous go a long way in achieving this.
Kevin Kupal, mindlist: "Look surprised, then look away for a while, then look at her then look surprised again. She may open a discussion. If not, open yourself by saying something like :
"You look strangely familiar. I swear I must have seen you somewhere. (pause). I can't remember yet. Let's switch it around. Do you HAVE THAT FEELING that you STRONGLY RECOGNIZE ME. Do you HAVE THAT FEELING NOW that I"M UNCANNILLY FAMILIAR.(?)"
Her (most likely response, if the principle works): "... yeah... I must have seen you from somewhere"
