No, it sounds like you were talking about Dead End Dada – that’s the second, 60-page story where the characters have a run-in with a psychiatrist. I have the paperback on my shelf – can you tell? 
I went here to get info on getting things autographed:
If you want Daniel and/or Jill to autograph something, send it along with a self-addressed stamped envelope, or a pre-paid courier envelope.
I also recall seeing him suggest that you mail him a book plate to autograph instead of the book itself if it was a rare item like the Norb comic collection.
