Three months after the deep-dish pizza nuclear explosion, Fitz finds out he married a dolphin, Rusty and Delbert conquer an island, and Randall develops an anal polyp that begins to take over his life and body.
Randall must prove to Karen that he's a good father by taking care of Hopson. Meanwhile, Delbert and Rusty open a carnival on the new island they conquered, Dusty goes to great lengths to attend the carnival, despite being confined to desk duty, and Bullet poses as a stuffed animal to get close to a sexy woman.
To keep Karen from drinking alcohol when she's pregnant again, Randall outlaws all alcoholic beverages leaving Bullet, Robby and Delbert to become Dukes Of Hazzard. Kevin lies to Gina of having a girlfriend in Canada.
