Anyone can do any amount of work, provided it isn't the work he is supposed to be doing.
~ Robert Benchley (1889-1945), U.S. humorous writer. Quoted in The Algonquin Wits (ed. by Robert E. Drennan, 1968). Benchley's own method is also quoted in the book, "I do most of my work sitting down. That's where I shine."
