Mark feels his friends don't respect him, and his mother babies him. In order to earn respect he joins a Karate class. His teacher kicks him out for being too wimpy. Cody agrees to help Mark prepare for the big karate tournament (Cody is a black belt) in a month and Mark becomes a totally new man. He faces the best person in the first match and falls behind quickly. Cody, however, notices his weakness and Mark uses it to catch up and force the guy to the final point. Mark loses the match, but wins respect from everybody except the coach of the other guy who mocks him and Cody and then challenges Cody to a karate match. Cody beats him badly. Frank is tired of all the yelling in the house so he installs an intercom that has a radio in it, but he is forced to destroy it when it wakes everyone up in the middle of the night.
