The Berenstain Bears (1985)

Forget Their Manners (2x3)

:

Mama Bear decides to take her ill-mannered family in hand and offers them lessons to become polite, but she realizes that she received better luck from children than Papa. Unsuccessful in her method, she devises a Politeness Plan - a chart listing a chore as a penalty for each act of rudeness. The cubs foil the plan by being super polite and actually enjoy it.
