"Honey, We're Stuck in the '70s" is the fourth episode of Honey, I Shrunk the Kids: The TV Show which premiered on October 17, 1997.
==Plot==
Wayne is testing out his new invention, the Szalinski Time Hopper. He tries to travel back to see the signing of the Declaration of Independence, but accidentally ends up in the Mesozoic instead. On his attempted return, he briefly ends up at Custer's Last Stand. Later, he brings Christopher Columbus to the present day and has to stop him from sneaking a modern globe back to his era. While conducting these temporal experiments, Wayne forgets his wedding anniversary, and struggles to make it up to Diane afterwards.
Meanwhile, Amy has a crush on her history teacher, Paul O'Donnell. He finds out when he catches her passing a note in class that mentions he's a "hottie." Later, he tells her in private that they can't be together. Amy is inconsolable until she hears that her father has invented a time machine. She decides to go back to 1976, when Paul would be the correct age for her to date, and blackmails Nick into operating the controls.
In 1976, Amy lands in the bedroom of Andy, a teenage boy whose family lived in the Szalinskis' house before them. She then heads for the school, where she hits it off with the young Paul. Just when they're arranging a date, the recall watch zaps her back to 1997. Nick explains to an outraged Amy that there's a built-in safety feature that returns time-travelers after two hours. She makes several more trips back to 1976, developing a relationship with Paul, but keeps getting recalled at inconvenient times. When she's pulled back just before she can accept his invitation to the prom, it's the last straw. Amy decides that she will live in the '70s permanently and ditches the recall watch.
Nick tells his parents that Amy ran away... to 1976! Wayne goes after her, wearing a stereotypical disco suit because that's how everyone dressed in the '70s, right? Enlisting the help of Andy, Wayne tracks down Amy, who in the meantime has become disillusioned with the '70s anyway. Wayne reveals that anything or anyone that stays in the past too long will crystallize, which is why he gave the recall watches a built-in time limit.
Wayne and Amy try to go back to 1997, but the Szalinski Time Hopper malfunctions. Since only Wayne knows how to fix it, and he's stuck in the past, he decides to build another time machine using 1970s materials. While Wayne, Amy, and Andy are collecting aluminium cans for the machine, Wayne encounters the teenage Diane, who tells him that she would like it if someone carved her name into the sweethearts tree. This new time machine also malfunctions, departing without its passengers and landing next to a group of cavemen.
Wayne comes up with a new plan. After carving something into the sweethearts tree, Wayne and Amy break into the school, where Wayne tells the teenage Diane to go to the sweethearts tree if she ever needs to get a message from someone she loves. Meanwhile, Paul tells Amy that he's dropped out of school so that he can completely devote himself to her. Amy tells him that he needs to stay in school in order to pursue his dream of becoming a teacher. Saying that she can't stand in his way, Amy breaks up with him. 
Back in the present, Diane suddenly remembers this whole incident. She and Nick go to the sweethearts tree, where they find Wayne and Diane's names carved into the tree along with the equation needed to fix the Time Hopper. While Wayne and Amy are being chased out of the school, they are suddenly zapped back to 1997. As the family reunites, Diane and Nick reveal that they also had some help from the grown-up Andy.
