Famous quotes containing the word table:
“... 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)
“The one happiness is to shut one’s door upon a little room, with a table before one, and to create; to create life in that isolation from life.”
—Eleonora Duse (1859–1924)
“When the painted birds laugh in the shade,
When our table with cherries and nuts is spread:
Come live, and be merry, and join with me
To sing the sweet chorus of ‘Ha, ha, he!’”
—William Blake (1757–1827)
