I have occasionally run into problems related to obtaining too large a fraction of my knowledge from books:
- I had no idea who Vera Lynn was when I heard that Pink Floyd song.
- I read the line "Then the fit hit the Shan," without ever recognizing the pun.
- The first I heard of the M25 London Orbital was that it was designed by a junior devil.
- I studied All the King's Men for clues to its State of residence.
But worst of all, this is probably still happening and I just don't know it.
