Here are the old lines I use to use:
* The word of the day is "legs", can you help me spread it around?
* Are you a box of lucky charms? Because you look magically delicious.
* Yes, I know you are impressive. That is why I can not stop staring at you.
* I am only sweet because you give me a reason to be sweet.
* Have sex with me, make me happy, and I will move your wishlist into your inventory...
* Good evening. My name is Don. What may your name be? A pretty name for a pretty girl.
* I know guys probably ask you this all of the time, but...may I have to honor of kissing a pretty girl in [insert scene here]?
* Go up to a girl eating candy and ask her, "I have never tried that before, may I have a taste?". If she says yes, then kiss her and say, "delicious". While she is in shock, holding her and nibbling her neck is fun.
* Go into a bar / club with a camera and a sign. Make up a fake friend / fake story about that friend standing you up to go on a business meeting or something boring like that. Then write on the sign, "This is what you are missing [insert friend's name here]". Tell the girls in the club your story and ask them if they can help you make your friend jealous by taking a picture with you and the sign. You will be surprised just how far some girls will go to help you...and how many phone numbers you will get.
