Heh, I know what you mean...every time I came across some kind of allusion to his other books (and he does the same in his other novels, even little things like how Rose has a copy of "Misery" (the fictional book, of course) near her at the beginning of Rose Madder) I congratulate myself on spotting it, hee. And praise King for adding all these links and creating his own world, with the Dark Tower series standing in the centre of it.

Ooh! Another moment (I knew I'd remember more). Well, not quite a moment, it's on-going. But the whole Jake and Roland's madness that builds and climaxes with Jake's entrance into Roland's world. Watching them both being torn apart by their conflicting memories is very memorable.
