I found this on another forum, but unfortunately I can't remember which to give credit. I've been using it with about the same success rate as "Perfect Internet Game."

Hey, you look kinda cool, but before I'd let you into my social circle I need to ask you a couple of really important questions. It's a scientific fact that the answers you give to these questions can really tell me a lot about you.

1) can you cook?
2) are you rich?

Some girls will write you really silly responses, for example:

1. I learned to cook in prison
2. why do you think I went to prision?

And then you can just take it from there. However, other girls will just write "1. yes 2. no" and leave it at that. In these cases and any time you can't think of a good followup to their response, you can just use:

Damn I have the same answers as you. I knew this wouldn't work out. We could never get along, we'd fight all the time... and then I'd win. But we can be friends. I'm Erik.

This will usually get them to introduce themselves or remark about how you wouldn't win and either way you can take it from there.
