How do I close an old account if I don't remember email/pwd for it?

So, years ago I created a FB account. Back then none of my friends were on, so I forgot about it, as well as which email address I used to create it and/or my password. I since created a new account and use it all the time, but the old one still shows up and has confused a lot of people, who think that THAT is my current account. Considering I know neither the email address nor the password for the old one, is there ANY WAY at all for me to disable it???
