this sounds lame but i use it often if i get heavy eye contact:
PUA: hey there, how much does a polar bear weigh?
HB: uhh, what? i dont know!
PUA: enough to break the ice

not that that's out of the way... hi, i'm hxc87x.
she already wants you to go talk to her, so you dont even need anything. you can just pop in there and introduce yourself, get her name and run into A2. i just like using the the polar bear thing because it always gets at least a soft giggle but you really dont need anything more than "HI!"
so after the initial introduction, throw in a quick line and pop into A2.
PUA: so do you always stare at guys and wait for them to come talk to you?
HB: blah blah
PUA: *neg* anyway... *you've now transitioned, so nows where you DHV*
