1944, James Thurber, letter to E. B. White in The Thurber Letters, New York: Simon & Schuster, 2002, p. 366, You are […] a man of powerful testicles and firmly rooted hair, capable of orgasms of a pretty high order and equipped with a curious kind of zingless lasting power. You may be dizzy and weak and you may buzz but you will outlast the Lou Gehrigs who run past you up the stairs three at a time.
