Famous quotes containing the words john and/or nash:
“People named John and Mary never divorce. For better or for worse, in madness and in saneness, they seem bound together for eternity by their rudimentary nomenclature. They may loathe and despise one another, quarrel, weep, and commit mayhem, but they are not free to divorce. Tom, Dick, and Harry can go to Reno on a whim, but nothing short of death can separate John and Mary.”
—John Cheever (1912–1982)
“How easy for those who do not bulge
To not overindulge!”
—Ogden Nash (1902–1971)
