One day in the middle of summer, Bob receives a package from the ladies who bought the restaurant that his dad used to own, Big Bob's Diner. In the box, Bob finds his old "toys" that he had played with in the restaurant when he didn't feel like working. When the kids hear his story about his childhood, they pity him because he mostly worked and had no fun. Later that day, Bob realizes he is doing the same thing to his kids that his father did to him, so he fires them and tells them to enjoy their summer vacation. After reluctantly agreeing to leave their jobs, the kids try to enjoy vacation activities but find their lives very boring without jobs at the restaurant.
While the kids are outside having a bad summer vacation, Mickey stops by for a visit after being released from jail because of a mistrial; the prosecutor was doing meth during the trial. Because Bob has been unable to hire new help, a reluctant Linda suggests that he hire Mickey. Mickey asks for just meals and a cot to sleep on in the basement. Bob agrees to hire him and Mickey begins his job by offering samples in the burger suit.
The kids find a blueberry farm owned by a hippie couple named Cooper and Beverly. Gene and Louise are hired to help them with their "weed" problem by harvesting marijuana from their greenhouse. Tina is the delivery girl delivering blueberries, unknowingly selling marijuana to customers, including Speedo Guy, Mr. Fischoeder and Marshmallow. Back at the restaurant, Bob is regretting his decision to hire Mickey when he finds out that he only sleeps in the basement because he has plans to rob the bank again, this time by digging to it underground. Mickey believes he is immune from prosecution because of "double jeopardy", only to find out from Bob that is incorrect.
Mickey is fired, and Bob tries to hire the kids back. He is shocked to find out that they have new jobs and tries to convince them to return to the restaurant. When they tell him what they are being paid he instantly changes his mind. Later that day, a pothead comes by with blueberries and asks Bob and Linda to tell Tina to refund him because the "blueberries" have too many stems and seeds. Linda opens the box to find the marijuana under the blueberries, and Mickey leads Bob and Linda to Cooper and Beverly's pot farm. When they get there, it turns out that the pothead was an DEA agent operating a sting, and SWAT teams and agents surround the farm.
In the end, the kids are rehired and Louise tells her class about why "blueberries" should be decriminalized.
