"If there was the possibility of becoming any speculative fiction character ever created (except your own), would you? Who? Why?
I’m pretty happy with who I am. When I was a kid I wanted to be Doc Savage, but you can see how that turned out. It might be cool to become John Carter, if for no other reason than to watch the death match between Dejah Thoris and my wife. Second thought, that has a lot of ways of ending in tears, and after Mrs. Ehart finished with that Martian heifer, I would probably be next."
And of course more smart-aleckey goodness on the other side of the link above.
