A number of years ago I was having a group of 9th grade students working
on some project where they needed to look up some info or pictures in
encyclopedias. I have a 24 volume set in my room. Someone wanted to look
up the flag of some country, so I went over to the book rack. Not there.
So I announced, very loudly, to the class "who's got the "f"
encyclopedia?" They all looked up at me, shocked! (try saying it fast,
out loud - you'll figure out what I mean...)
