Famous quotes containing the words pocket, set and/or theory:
“At a time when pimpery, lick-spittlery, and picking the public’s pocket are the order of the day—indeed, officially proclaimed as virtue—the poet must play the madcap to keep his balance. And ours.”
—Studs Terkel (b. 1912)
“Prudence suspects that happiness is a bait set by risk.”
—Mason Cooley (b. 1927)
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
