Famous quotes containing the word table:
“The table kills more people than war does.”
—Catalan proverb, quoted in Colman Andrews, Catalan Cuisine.
“Many a time I have seen my mother leap up from the dinner table to engage the swarming flies with an improvised punkah, and heard her rejoice and give humble thanks simultaneously that Baltimore was not the sinkhole that Washington was.”
—H.L. (Henry Lewis)
““A sigh for every so many breath,
And for every so many sigh a death.
That’s what I always tell my wife
Is the multiplication table of life.””
—Robert Frost (1874–1963)
