Here's an interesting thing. Apparently a large number of people who read these popular childrens books remember them as the BerenSTEIN bears, spelled like that, and only recently discovered, when it was brought to their attention, that all copies, including their own, actually read BerenSTAIN. So strong is the conviction that it seems to have spawned a "parallel universes" debate on the internet. Check it out. I was drawn into this in a minor way because I seem to remember "Interview With A Vampire" rather than "Interview With THE Vampire" and even though I'm quite prepared to believe I am mistaken...it kind of bugs me.
