I was just installing 12.04 beta2 when I noticed something really odd. I was at the screen where you enter your username/hostname/password/etc. I typed 'Me' for my real name as I normally do. This is the weird part. The installer filled in the hostname as 'me-###-##5-1544' where the ###-##5-1544 is my parent's land-line phone number (about two hundred miles west of where i am). Where did the installer get that number? I am installing over a previous install of ubuntu, but that was a throw-away install that I never put that number on. I have other partitions and other OSes on this hard drive, but none were mounted at the time of install and none were selected to be used as mount points in the previous screen.
Picture of what I'm talking about:
