Famous quotes containing the words small and/or engines:
“A small town is automatically a world of pretense. Since everyone knows everyone else’s business, it becomes the job of the populace to act as if they don’t know what is going on instead of its being their job to try to find out.”
—Jeanine Basinger (b. 1936)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
