"a little caricature of Carter that is placed throughout the book"
Man, just like "Atari BASIC: XL Edition" that I learned a ton of BASIC with as a kid. It had "Kilroy" (as in "... was here") throughout it.
I vividly remember reading some of that book while on a trip to the department store with my mom. In fact, not only do I still HAVE that book (surprised? don't be... I was the "Atari vs Dell" guy on Slashdot the other day), it's on the shelf next to me, and just yesterday I happened to grab it when I responded to one of those dumb chainlettery things on Facebook ("grab the closest book, open page X, type sentence Y as your facebook status").
This is starting to freak me out. ;)
