Famous quotes containing the word table:
“The gingham dog and the calico cat
Side by side on the table sat;”
—Eugene Field (1850–1895)
“Comes the time when it’s later
and onto your table the headwaiter
puts the bill,”
—Robert Creeley (b. 1926)
“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 (1817–1862)
