The Schoolmaster - S1.E52

After Congress declares the American republic can only become a great nation by schooling its people, Lucky saves a haughty, pedantic East coast teacher who immigrates to civilize the West and arrests three crooks who were robbing the teacher. The ignorant town-folk soon mistrust the hot-head educator. The local crime baron Jolly Potbelly forbids turning the saloon into a school for both adults and youth. Lucky stays as protector and armed truancy-fighter, but is ordered on the benches too as 'role model', later even as substitute.
