Return of the Man Who Says Palimpsest

Yesterday I went to see the doctor (some things are none of your business!) - not Dr. "M.," the regular doctor! Anyway, she used the word "violaceous." And I was like, "Good one, Doc!" It reminded me of the time a few weeks ago when I ran into the man who says "palimpsest" at the City Grocery Bar. During a brief conversation on amiable bar-related topics (specifically, the trough system employed in the men's room), this fellow quite casually used the words "expatiate" AND "interregnum." And he had had a few beers! But he didn't let that stop him! I meant to tell you before.
