The episode starts off with Mario and Rosalina trying to get Jeffy to eat his green beans. Suddenly, The Breaking News report plays with Goodman stating that world-renowned Painter, Jacques Pierre François has died, and states that he reportedly shot himself in the head making a Painting called "The Suicide", and left his million dollar fortune to his only child whose identity is currently unknown, which is jeffy.
Rosalina states that the news is sad but Mario doesn't know who the painter is and while Rosalina is telling Mario about how he got famous for Stuffing paints up his nose and sneezing them on a Canvas Jeffy was dumping his Green beans behind the couch and then told Mario that he ate all of his green beans which prompts Mario to ask if the Green Beans are behind the couch which Jeffy replied "No", Mario Looks behind the couch and sees the green beans on the carpet catches scold Jeffy and told Jeffy to go into the corner right before he received a Phone Call from Goodman.
Mario then told Jeffy to go into the corner again which Jeffy responds to "What the hell is a Corner?" Mario answered the call and Goodman Greeted Mario with "Uh Hi is this Mario? The Guy that chainsawed a couch in my Apartment Complex?" stating that a woman in the office just spoke with him and is looking for Jeffy. Upon hearing this, Mario instantly gets overjoyed. He and Rosalina get Jeffy ready to see his real Mom at the front door.
Jeffy's mom shows up at the door and is revealed to be an alcoholic, a smoker, and a prostitute. She introduces herself as Nancy, and asks for alcohol, despite being pregnant. She then proceeds charge Mario a dollar to spit on him, even though Mario said no. Mario asks Nancy why Jeffy was dropped off with him, to which she responds that she just needed somebody to watch him while she was at the grocery store. Mario asks her why it took her a year to go to the grocery store, in which Nancy said it was hard to find. But Jeffy ends up telling what really happened:
One year prior, Nancy drives Jeffy to the apartment complex, where she intends to abandon Jeffy at. Jeffy doesn't want to leave Nancy, but Nancy does, because she thinks Jeffy is ugly, stupid and a waste of her time. Jeffy asks what to do if he forgets his name, so Nancy writes it on his shirt (which pretty much explains that). Nancy then puts a note on Jeffy's shirt that says "Please Babysit....sorry", and lies to Jeffy by saying it says he's a good boy. Nancy drives off, leaving Jeffy at the apartment, so Jeffy looks for a door to knock on. He comes across Mario's apartment door, and we then see the scene from Mario The Babysitter! that shows Mario meeting Jeffy for the first time.
Back in the present, Nancy beats Jeffy for "lying". Mario tells Jeffy to leave with Nancy, but Jeffy and Rosalina are both reluctant. Nancy eventually forces Jeffy out. Mario says “Well, he’s gone now!”, but Rosalina is now furious at Mario for letting Nancy take Jeffy away, and when Mario says that he thinks it's good that Nancy beats Jeffy, Rosalina breaks up with him and leaves in anger. Meanwhile, Jeffy still does not want to go with Nancy. Nancy then tells Jeffy that his father was a famous painter who passed away that day and that he left millions of dollars to Jeffy, so when Jeffy turns 18, all the money would be Nancy's.
Meanwhile, Mario begins to miss Jeffy, even playing his cat piano. He even pretends he is happy. Jeffy tells Nancy that he is hungry, to which Nancy says that he must wait a week until the check comes in before he can eat again. Jeffy then escapes out the car window and runs back to Mario's house. He begs Mario to let him stay, but Mario still refuses at first, but decides to let him in until Nancy returns to pick him up.
A few minutes later, Nancy arrives and lies to Mario that she was getting Jeffy a Happy Meal from McDonald's and he ran away. Mario then makes a call and tells Nancy and Jeffy to sit down. Nancy starts beating Jeffy senselessly, only for Brooklyn T. Guy (as a cop) to arrive and arrest Nancy for prostitution, child abuse and some other things.
Mario considers sending Jeffy into foster care, but feels bad for him and reluctantly decides to adopt Jeffy. Brooklyn T. Guy then gives Mario a ripped piece of paper he found in Nancy's purse. Mario realizes he has the other piece to it. The note was from Jaques Pierre François and Mario and Brooklyn T. Guy find out he was his father. Mario thinks Jeffy could live with Jaques but Brooklyn T. Guy reminds him of his death and how he left all his money to Jeffy but he doesn't actually get it until he's 18. He then tells Mario if he's a good parent he could get some of the money in 6 more years. Mario now fully accepts to be Jeffy's adoptive father.
One day later, Mario, Rosalina, and Jeffy are all sitting together on the couch, with Jeffy playing his cat piano. Rosalina asks Mario why he won't tell Jeffy to stop, to which Mario responds: "Not today. Not right now. This one's for me.", then the video ends.

Logan announced Jeffy's Parents! and The Quiet Game! as the first videos of 2017. Logan said Jeffy's Parents! would be released on the 24th of January 2017 in the description below. But instead, it was released on the day before, which was the 23rd of January, being one day before being a full year since Mario The Babysitter! was uploaded. This was likely due to the thunderstorms and tornadoes presently going on around Cantonment, Florida, which was also the reason for the delay of The Quiet Game!

- His mom acted insanely weird and was an alcoholic prostitute.
- It's most likely she never takes him to school throughout his entire life due to her lack of responsibility.
- It is revealed at the beginning of the video that Jeffy's mom drinks while pregnant, hinting that she might be drinking alcohol while she was pregnant with Jeffy and messed him up.
- Along with those reasons, Jeffy could be just plain-out dumb.
- However, he is sane enough to apologize to Mario and admit what he has done, so he was half and half.

In any case, Nancy will not any part of the money since she doesn't have custody of Jeffy anymore.
- Goodman is still mad at Mario about the couch incident three months ago, even though it was Wendy O. Koopa who cut the couch in half.
- This video had different angles than other SML videos, such as the argument and brief breakup between Mario and Rosalina.
- This shows Jeffy's sane side once again remembering what happened when he was dropped off at Mario's door, knowing to how to sneak out of the car and go to Mario's house, and knowing that what would happen if he either went with his mom or a foster care, even knowing how to plead Mario to adopt him. He even apologized to Mario and admitted his mistakes and didn't play the cat piano.
- The likely reason why Jeffy wears a helmet is to protect him of being beat on the head by his mother. It's unknown if his father or Jeffy himself put the helmet on, or he wants to be like his father who wears a beret.
