Always Knock the Postman Twice is the tweleth episode of Teacher's Pet from Season 1.
When Scott makes slanderous insults against a mailman during "Career Day" (Going back to his dog instincts) and ends up getting in trouble for it, Leonard tries to change Spot's prejudice against mailmen by explaining to him all the mistakes that Spot and the other dogs see about mailmen before he gets himself into more trouble at school.
