Karate Kid (S04E01)

Mark feels undervalued by his friends and overly coddled by his mother. Determined to gain their respect, he enrolls in a Karate class, only to be dismissed by his instructor for lacking toughness. With Cody, a black belt, stepping in to help him train for an upcoming tournament, Mark transforms significantly. During his first match, he struggles against a top competitor but, with Cody’s guidance, he identifies and exploits the opponent's weakness, making a strong comeback. Although he ultimately loses, he earns the admiration of his peers, except for the rival’s coach, who taunts him and challenges Cody to a match—where Cody triumphs decisively. Meanwhile, Frank grows weary of the constant noise in the house and sets up an intercom system with a radio. However, he ends up having to dismantle it after it disrupts everyone’s sleep in the middle of the night.
