In this episode, Bart and Lisa refuse to accompany Homer and Marge to their uncle's birthday, so the parents decide to have a romantic vacation by themselves in Miami instead.
Marge stops them after Maggie is accidentally thrown into a box of cat litter and tells the pair that they are going to Ohio to celebrate Uncle Tyrone's birthday.
Bart, Lisa and Grampa learn on the news that the hotel in Dayton where Marge and Homer are supposed to be staying has been completely wiped out by a tornado.
Homer and Marge see the children waiting for them outside their hotel room door, so they run from the ready-to-track-them-down pair, causing Bart and Lisa to summon a hot pursuit of their parents in an instrumental musical montage and an animated sequence.
The next day, Bart and Lisa, feeling a little guilty, decide to give their parents some space, and go to an amusement park, inadvertently running into Homer and Marge who snuck off for some time alone.
Refusing to allow Lisa to explain, an angry Homer and Marge start running away again and find refuge in a giant inflatable castle, which their lovemaking antics cause them to fall into the Niagara River.
Homer and Marge shout they are more alive than any of the boat's squares from inside the inflatable castle, as it floats away, and they engage in martial artistic sexual intercourse underneath the falls.
Meanwhile, back in Springfield, Ned and Rod Flanders receive their monthly credit card bills and gasp at the charges Homer and Bart have run up.
[8] On Four Finger Discount, Guy Davis did not like the episode, but Brendan Dando related to certain scenes because he was a parent although he thought the writing was "absurd".
