Foreign chick opener

A little while back I saw a group of Asian people sitting at a nearby table at a restaurant. I totally dig foreign, especially asian chicks. At that time I just couldn't think of any way to go talk to them.

Had an idea for an opener today:
"I was just making a bet with my buddy that I can guess people's nationality - let me guess - are you guys from [some country]?"

Shows you as open-minded, international etc, gives you stuff to talk about, and if you guess wrong (like India instead of Pakistan, or any other pair of countries that don't particularly like each other) it will even get them emotional.

Should work great, I'm itching to find a group of foreign-looking people to try it on.
