One company I worked for had a password-changing program that looked up a huge database of 3 letter words and created a subfile page of 6 letter words constructed from 2 three letter words. The user had to choose one of these randomly paired words.
For example, the program may put dad and lip together to make dadlip. If the user didn't like any of the sixty or so words suggested, they could refresh the screen and get another load. The idea was okay, but I found it a bit of a nightmare as a user.
