I once used a password which our IT department gave me and it was !'a;@,oq and at least for me it looked random enough. I had it as a root password on a server and I enabled password login for about 2 minutes because I wanted to resize some virtual hard drive or something and couldn't be logged in as a normal user and then switching with su to root because then the normal user would have open files on the file system and I wouldn't be able to unmount or something. Within those 2 minutes some chinese hacker scripts took over the server and started DDosing some chinese IP adresses. We had to shut it down and blast it and set it up from scratch again. I later found out that this password was everything but random. It was difficult for me to see because I've been using Dvorak for a couple of years now and didn't see the pattern that it was just the first two rows of the characters on a qwerty keyboard. So actually it was !qaz@wsx (I just put the Dvorak version on top of the comment to give you the same unknown feeling for the password which I had back then.) I've never reused any passwords since then and always create new ones with my password manager.
