I once overheard a girl in one of my college English classes talking about her upcoming teaching career. She raved about having her summers off, the tenure she gets in three years and a day, but spent less then a minute talking about her goals for her students.
Elizabeth Halsey, as portrayed by Cameron Diaz, in the hilarious comedy, Bad Teacher, substitutes movies for books, takes no interest in her students and sleeps at her desk either stoned or nursing a hangover, which is exactly how I imagine that same girl now runs her classroom.
