Famous quotes containing the words typical, values, thrust and/or engines:
“It was announced that the trouble was not “malignant.”... It was a typical triumph of modern science to find the only part of Randolph that was not malignant and remove it.”
—Evelyn Waugh (1903–1966)
“Tallulah [Bankhead] was the foremost naughty girl of her era but, in those days, “naughty” meant piquant, whereas values have so changed that now, in the 1970s, it generally means nauseating.”
—Anita Loos (1888–1981)
“In my stars I am above thee, but be not afraid of greatness. Some are born great, some achieve greatness, and some have greatness thrust upon ‘em.”
—William Shakespeare (1564–1616)
“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)
