Warner Brothers 1989 Movie directed by John G. Avildsen. Morgan Freeman as Principal Joe Clark.
Principal Joe Clark: I want all of you to take a good look at this slovenly, sloppy boy - as an example of how NOT to dress. If you look like THIS in the morning, find some other clothes to wear. Self-respect permeates every aspect of your existence. If you don't have respect for yourself, you're not gonna get it from anyone else.
