Chatterbox: Down to Earth

OK, this is random, but I'm starting to worry that someday I'll run into one of you by accident and never know it. That would be tragic. So I vote that we Chatterboxers come up with some phrase that we incorporate into the first conversation we have with any person, so that we will never meet each other and not know it. I'm sorry, but I'm starting to get paranoid about it. :P Suggestions as to what this Chatterboxer phrase could be?
