He mentioned kirk/spock. He mentioned denny crane/alan shore. He mentioned T.J. Hooker/???? and said "I guess I had a way with a nightstick." And then he said he hoped no one ever slashed his character from the Twilight Zone episode "Nightmare at 20,000 Feet" with the gremlin on the wing.
Since this book came out in 2011, I think the chances are good that someone has actually done this.
(If you haven't read his quote, Google "shatner nightmare at 20000 feet slash" and it'll bring up a link to a google books with the info highlighted. And no, I didn't find any actual Twilight Zone slash for his character in that ep, but I'd still bet it's out there.)
