Famous quotes containing the words magic and/or number:
“We’re not blind and we’re not fools. We’re just plain, sensible people who refuse to be fooled by a lot of supernatural nonsense.... There’s no magic in dried lizards and dead chickens.”
—Eric Taylor. Robert Siodmak. Frank Stanley (Robert Paige)
“This nightmare occupied some ten pages of manuscript and wound off with a sermon so destructive of all hope to non-Presbyterians that it took the first prize. This composition was considered to be the very finest effort of the evening.... It may be remarked, in passing, that the number of compositions in which the word “beauteous” was over-fondled, and human experience referred to as “life’s page,” was up to the usual average.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
