Steve and Carl are defenseless when they get robbed--until they step into Steve's transformation machine and become karate experts. Laura gets a nose ring.

Steve is put in charge of building the school's homecoming parade float. With some difficulty, he gets volunteers to build a beautiful float. Unfortunately, while transporting it to the school, Steve crashes the float and destroys it. Mother Winslow sustains a series of minor injuries in her strenuous hobbies, including karate and square dancing.

When Laura and Steve both end up without dates for the senior prom, they decide to go with each other. Steve tries very hard to make it a special night for Laura, and the evening ends with a romantic kiss. The Winslows' unpleasant neighbor wants them to tear down Carl's fence so he can build a barbecue. When Harriette and Carl object, it results in a nasty confrontation.
