microsoft bob
An operating system made by Microsoft in 1995.  Instead of a "desktop," it used a "room," where all your programs were objects lying around the room.  It also had little talking characters (including a dog named Rover) which tried to give helpful advice but were usually just annoying.  If you've never heard of it before, do a search on it or something.
Have you ever used Microsoft Bob?  That talking dog is so f*cking annoying!
