I've run into the second quote in real life all too often!

-- Robert Heinlein

"Rudeness is the weak man's imitation of strength."
-- Eric Hoffer

"She was a woman who, between courses, could be graceful with her elbows on the table."
-- Henry James

"The author of the Iliad is either Homer or, if not Homer, somebody else of the same name."
-- Aldous Huxley
