“I respect kindness in human beings first of all, and kindness to animals. I don't respect the law”
As quoted in The Harper Book of Quotations (1993) edited by Robert I. Fitzhenry, p. 420
Context: I respect kindness in human beings first of all, and kindness to animals. I don't respect the law; I have a total irreverence for anything connected with society except that which makes the roads safer, the beer stronger, the food cheaper and the old men and old women warmer in the winter and happier in the summer.
