Famous quotes containing the word table:
“A big leather-bound volume makes an ideal razorstrap. A thin book is useful to stick under a table with a broken caster to steady it. A large, flat atlas can be used to cover a window with a broken pane. And a thick, old-fashioned heavy book with a clasp is the finest thing in the world to throw at a noisy cat.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“... So damn your food and damn your wines,
Your twisted loaves and twisting vines,
Your table d’hôte, your à la carte,
. . . .
From now on you can keep the lot.
Take every single thing you’ve got,
Your land, your wealth, your men, your dames,
Your dream of independent power,
And dear old Konrad Adenauer,
And stick them up your Eiffel Tower.”
—Anthony Jay (b. 1930)
“In this sad state, God Tender Bowells run
Out streams of Grace: And he to end all strife
The Purest Wheate in Heaven, his deare-dear Son
Grinds, and kneads up into this Bread of Life.
Which Bread of Life from Heaven down came and stands
Disht on thy Table up by Angells Hands.”
—Edward Taylor (1645–1729)
