We were in his apartment in Chicago, and Oprah - who back then was a local talk-show host in Chicago and had not yet gone national - came on the TV which was on in the background.
John looked up from what he was doing at the the TV, paused, and said dryly:
"Oprah, you fat blob."
Then he looked back down and continued reading.
'Nuff said.
Can you find a couple of pictures from that show?
