" A boy will nearly always run after anything that is running, and his first impulse is to throw a stone at it. This is a survival of primeval man, who must take every chance to get his dinner. So, when Penrod and Sam drove the hapless Whitey up the alley, they were really responding to an impulse thousands and thousands of years old—an impulse founded upon the primordial observation that whatever runs is likely to prove edible. Penrod and Sam were not "bad"; they were never that. They were something that was not their fault; they were historic. "

― Booth Tarkington , Penrod and Sam
