The Berenstain Bears (1985)

S2E3 Forget Their Manners

Mama Bear takes it upon herself to teach her unruly family some manners, but she finds that training the children is easier than dealing with Papa. After her initial attempts fail, she creates a Politeness Plan—a chart that assigns chores as consequences for every rude behavior. However, the cubs turn the tables by being exceedingly polite, embracing the challenge, and even having fun with it.
