Famous quotes containing the words double and/or check:
“Today, San Francisco has experienced a double tragedy of incredible proportions. As acting mayor, I order an immediate state of mourning in our city. The city and county of San Francisco must and will pull itself together at this time. We will carry on as best as we possibly can.... I think we all have to share the same sense of shame and the same sense of outrage.”
—Dianne Feinstein (b. 1933)
“This fellow is wise enough to play the fool,
And to do that well craves a kind of wit.
He must observe their mood on whom he jests,
The quality of persons, and the time,
Not, like the haggard, check at every feather
That comes before his eye. This is a practice
As full of labor as a wise man’s art.”
—William Shakespeare (1564–1616)
