 Officer Kirk comes to Arnold s to make a few announcements: First, he s the new acting sheriff, and second, he plans to drive several hoodlums out of town. One of the names he reads is Fonzie; when questioned by the Fonz, Kirk explains that he "doesn t like anything" about him. The bravado Fonzie shows around Kirk is just a cover - he s really troubled by the officer s constant harassment. Richie decides to write a letter to the editor of the Milwaukee Journal, while Howard - who is also considering contacting the mayor about Kirk s power-hungry attitude - calls a meeting of the Leopard Lodge to pressure Kirk into stopping his harassment campaign. However, Kirk somehow finds out what s going on, shows up at the Cunninghams and tries to intimidate the Lodge members into backing off (by threatening such things as ticketing the group for unlawful assembly, revoking Arnold s dance floor permit, citing Mr. Malph for a sign variance violation and taking away Howard s loading zone). Eventually, Kirk learns that Fonzie is at Arnold s and goes in for a late-night confrontation. Fonzie agrees to leave town, under the condition that he will now deal with Richie (who comes in clad in a leather jacket and greased hair). Kirk says he will be more than glad to deal with Richie, but then Potsie, Ralph, Joanie, Howard, Marion, Al ... and a bunch of teen-agers - all dressed in leather jackets, plain white T-shirts and blue jeans (except for Marion, who has on a skirt instead of jeans) - show up. Kirk eventually realizes he s outnumbered and concedes defeat. Everyone decides to celebrate with an impromptu sock hop.
