@Gilgalid No, you're not the only one. The joke does not work for me, and I'm a native speaker (I even TEACH ESL!). I came independently to the same conclusion as others, but only by warping the words in different ways. When I say "Pink Pinkness" over and over again quickly, I get "pinkpinknespinkpinknespinkpinknespinkpinkness". Apparently, Sanderson drops k's when he talks fast and uses vowels differently than I do.
