"Geriantics" (also known as "Geri-Antics") is the twenty-sixth episode of the fourth season, and the one-hundred-seventy-fifth episode of The Loud House.
When Lisa realizes that Pop-Pop won't be around forever, she turns to science to ensure his longevity.
Synopsis
At nighttime, Pop-Pop is reading a science book to Lisa so she can go to sleep. When Pop-Pop asks Lisa asks how her latest project is coming, Lisa states that her teleportation technology is working well and states that it will be effective in 73 years. This makes Pop-Pop state that he won't be around in 73 years, given his current age. The moment Pop-Pop says that, Lisa fears about Pop-Pop's lifespan and believes that she must rely on science to ensure his longevity.
The next day, Lisa brings Pop-Pop to the mall to work on his cardio by having him run while being pulled on an animal rider operated by Lisa. After that Lisa and Pop-Pop are at Sunset Canyon, eating lunch. While everyone is given steak, Lisa suggested to the chef to give Pop-Pop a raw fish instead for breakfast, lunch and dinner, much to his disappointment. Lastly, Lisa has Pop-Pop live in unusual room temperatures, such as having his room being heated up to 90 degrees, and swimming in the pool in ice cold water for 30 minutes. With her day over, Lisa gives Pop-Pop a pamphlet and wishes for Pop-Pop to follow her instructions.
The next day, Lisa decides to spy on Pop-Pop to ensure that he's following her instructions. However, she soon realizes that Pop-Pop is going against her wishes, as he gets a pedicure instead of going on a run, eating pancakes after his dose of fish, and swimming in warm water. Realizing she needs work to do, Lisa promptly makes Pop-Pop a suit with several mechanical features to ensure his longevity, and Pop-Pop agrees to wear it for Lisa's sake. However, Pop-Pop soon realizes the downsides of wearing the suit, such having to recharge it for 3 hours 5 times a day, being unable to go outside in day or night, or touch anyone else, since it would damage the sensors on the suit. This makes Pop-Pop have a talk with Lisa, saying that while her intentions are pure, she's not only causing trouble for him, but for herself as well. He explains that while he may not be able to live forever, he says that he still has a lot of time ahead of him and states that he would live those days to the fullest. Seeing his point of view, Lisa agrees to let Pop-Pop take the suit off.
Lisa allows Pop-Pop to resume his regular lifestyle.
Later, Lisa and Pop-Pop toss the suit away and Pop-Pop decides to join his friends in a game of shuffleboard. Seeing how happy he is, Lisa tells Pop-Pop to keep being himself. At that moment, Scoots drives by the dumpster with the suit and decides to take it, proclaiming she'll be living for a long time.
The title of this episode was originally the title of the Season 3 episode "Insta-gran".
When Lisa is on her way to bringing the suit, she is briefly humming part of the show's theme song.
Irony: Lisa's high tech suit requires three hours of charging five times a day, meaning that the user of the suit would spend most of their time recharging it than living the day.
