Like this one. Good stuff.

You can also imply the possibility of a relationship by playfully telling her you're going to teach her how to do something. I tell Brazililan chicks I'm going to teach them English, then follow it with a routine where I teach them how to say "Fish," "Ball," and "Cat" in English. When you say the three of them together, it sounds like the Portuguese phrase for "I gave a blowjob" which immediately takes it back into playful territory.

But you can tell her you're going to teach her how to cook, skydive, whatever, the more playful the better.
