Famous quotes containing the words list, number-one and/or country:
“I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.”
—Ernest Hemingway (1899–1961)
“I’m your number-one fan.”
—William Goldman (b. 1931)
“The man’s an M.D., like you. He’s entitled to his opinion. Or do you want me to charge him with confusing a country doctor?”
—Robert M. Fresco. Jack Arnold. Sheriff Jack Andrews (Nestor Paiva)
