Okay I actually got this opener from the show Heroes, haha. Not too sure how this will play out on the field if a lot of people watch that show... I haven't field tested it either, so I'll get back to you on this. Anyone is free to criticize or improve upon this.
PUA: So what are you?
HB: What?
PUA: Are you a robot ...(pause) or an alien? Because everyone is one or the other. Robots do what they are told, stick with the herd. Aliens, on the other hand, do their own thing.
Now if they choose either, come up with a playful neg response.
Option 1 (Robot): Aww you're no fun... I thought you were [adventurous,energetic,etc.]!
Option 2 (Alien): You sure do look odd for an alien (then give whatever physical neg you want here).
From here, go into whatever routine you have and have fun!
