Did anyone else notice that the mailbox in the short "Mailbox", bears simularities to Bill Cipher? They both know all. I have a theory that the mailbox IS somehow Bill. Or at least Bill's writing the letters to Dipper and Soos through it. Yes, i know theres not much proof, but it seems almost definte that there is some kind of connection between Bill and the Mailbox.
