Are you sure it isn't in my dictionary?
His example of "This little piggy went to market" shows the problem. That is in my password dictionary. When the "make up a password from the 1st letter of words from a song" started to be popular, I ran a small poll asking people to write a line from 3 Beatles songs and 3 songs by a popular country artists. Several hundred people responded and there were less than 100 unique lines and 10 lines were common to something like 80 or 90% of the respondents. The result of separating the lists based on their likely musical taste resulted in some scary guesses on which lines they would pick. When the same thing was run latter without requesting the specific musicians, the results were tainted by the previous request.
