What you don't know can hurt you

I don't know something. And even if I did I couldn't tell you. But I don't. How can I tell you something I don't know? Basically I can't tell you what I don't know, so don't ask... But what if I did know? That's just stupid, I already said I don't know. I'm not going to waste my time answering what-ifs. But it still hurts. What is "it"? I don't know, don't ask me.
