Famous quotes containing the word table:
“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)
“The newspaper is a Bible which we read every morning and every afternoon, standing and sitting, riding and walking. It is a Bible which every man carries in his pocket, which lies on every table and counter, and which the mail, and thousands of missionaries, are continually dispersing. It is, in short, the only book which America has printed, and which America reads. So wide is its influence.”
—Henry David Thoreau (18171862)
“When you got to the table you couldnt go right to eating, but you had to wait for the widow to tuck down her head and grumble a little over the victuals, though there warnt really anything the matter with them. That is, nothing only everything was cooked by itself. In a barrel of odds and ends it is different; things get mixed up, and the juice kind of swaps around, and the things go better.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
