King, Stephen Easter Egg - Stephen Himself in Tommyknockers

In Book II, Chapter 8 (Ev Hillman, Section 10 he talks about Bobbi's writing and says "she wrote good old western stories that you could really sink your teeth into, not all full of make-believe monsters and a bunch of dirty words, like the ones that fellow who lived up in Bangor wrote."

That fellow in Bangor is Stephen King.
