Famous quotes containing the word table:
“A man who can dominate a London dinner table can dominate the world. The future belongs to the dandy. It is the exquisites who are going to rule.”
—Oscar Wilde (1854–1900)
“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)
