So I recently pulled this one out of nowhere at a party and it worked pretty well.
I was doing the "How do you guys know each other" when someone asked for my name.
HB- I didn't get your name?
me- Mike. (Pretty damn common, I know)
HB- Oh I know so many Mikes! (This is where it clicked into my head)
me- Alright, how about you give me a new one? What would you say I look most like?
HB- haha.. I don't know. Maybe a _______.
me- Thats a pretty lame one, I want a cool one like DJ Master M or something.
HB- haha.. ok, what about __________.
me- aha.. I like that better.
etc...
Although I didn't get the number she is bound to remember me.

Would love to hear some feedback.

I love it and I'll tease her with it for example if she says your name should be ben i'd say:

"Mmmm it's mediocre. What about sexy ben" with a cheeky smile in a flirty way

Or whatever she says you can try and rhyme it with something like if she says nick I'd say:

"You wanna call me a dick?!?!" again delivered in the same way of course but u get the idea.

Anyway great idea man.

When she says she know many of me I was thinking of incorporating "Well that doesn't make me special does it?"
