I've used this one a couple times...

It's kinda hard to use one a single set but if you can more power to you.
Just approach and simply say "I only have a minute but can I ask you guys a question?"

-I usually skip straight into a introduction here to avoid any CB.

"My name is ____. and your's?"...

-shake hands, exchange cheek kisses, whatever you think is appropriate. For some extra kino with your target you can use some Stealth PU like pretending not to hear her name and leaning in but maintaining eye contact.

-Then I just run the question. "Ok, What's the worst pick up line you've ever heard?"

-Let them say theirs, add some negs and what not. Then you can say yours. Use one you've heard or even used before.

-I made one up just to give you guys.

So, here..."I saw a guy use this. He walked up to a girl and handed her a pen and clipboard. He said 'can you sign this and put your number down, I'm here to deliver the whole package.' Saying that he flexed." Then just ask how your set would handle that situation...I usually leave for a sec when the target wants to say hers, asking her to hold my drink and I'd return shortly. Come back and isolate my target....But you can do whatever you want since it's your unique style.

Good luck and play hard,
