The phrase “The best laid plans of mice and men” was first used in a poem called “To a Mouse” by Robert Burns, “The best laid schemes o’ mice and men/ Gang aft a-gley;/And leave us naught but grief and pain/For promised joy.” The “of mice and men” part was used as the title to a popular John Steinbeck novel, “Of Mice and Men”, now a well-known moral fable, stage play, and movie.
