"Jeffy's Wifi Problem!" is the 359th episode of SML Movies.
The video starts with Jeffy playing Rocket League. Jeffy scores a goal and starts trash talking. Mario then comes into the room and tells Jeffy to do his chores, but Jeffy say's it time for him to do his chores. Mario asks again and Jeffy says he's playing Rocket League and to not disturb him. Mario says he is going to change the wi-fi password if Jeffy doesn't do his chores. Jeffy responds "I don't give a shit", prompting Mario to change the Wi-Fi password from 1234 to ABCD and Black Yoshi's Call of Duty stops and disconnects.
Black Yoshi is horrified, saying "The poofis has been disconnectiss!" Mario then tells Black Yoshi the new password but tells him not to tell Jeffy. Shortly later, Jeffy screams “DADDY!”. Mario comes in and he was notified the “game” Jeffy was playing froze. Jeffy then tells Mario to tell him the new password. Mario continues to tell Jeffy to do his chores, and once Jeffy does his chores. Mario will tell him the new password.
Jeffy's chores are to do the dishes and dust the whole house.
Once Jeffy begins his chores he starts off with the dishes, he begins throwing plates on the floor, including a mug.
After Jeffy is done with the dishes, he starts dusting the house. Jeffy is first seen beginning dusting the red couch, and the PS4 controller, and whacks Mario with it. Mario gets annoyed by Jeffy when he hits him with the feather duster and asks Jeffy if he's all done with his chores. Jeffy answers yes to the dishes and dusting the whole house. Mario then makes Jeffy see how well he's done on the dishes.
Back in the kitchen, Mario notices that Jeffy didn't wash the dishes, but Jeffy thinks he was only supposed to do the dishes, suggesting only the plates and the mug. Mario asks Jeffy where he put the plates, Jeffy says the cabinet, Mario then checks the cabinet, but nothing is inside. Jeffy then remembered that he put them on the floor. Mario catching along, he looks at the floor only to see the shards of plates scattered all around the kitchen floor. Mario then asks that if Jeffy broke anything else, Jeffy is seen dusting from before in a different room, pushing vases with the feather duster. Mario then tells Jeffy he's not giving him the password.
Jeffy yells at Mario saying he did his chores and deserves the wifi password or else Jeffy will poop in the sink. Jeffy declares to get the Wifi password.
Later, Mario gets a phone call, Jeffy being behind the couch while on the phone acting as an internet company person. Jeffy tells him he has a security breach on his account. Jeffy however finds this suspicious so he look over the couch and found Jeffy. Mario yelled at Jeffy so Jeffy called the electrician. The electrician ask what he want and Jeffy said he doesn't know his WiFi password. The electrician ask why he couldn't just ask his parents and Jeffy respond that his dad doesn't let him so Brooklyn T.Guy then went to talk with Brooklyn T.Guy
Brooklyn T.Guy then went to the couch with Mario and Mario ask what he is doing here and Brooklyn T.Guy forgot so he then decided to show pictures in his phone. He ask him for a WiFi password and Mario said he could use his so he did. Then Brooklyn T.Guy show him 2 pictures of the Leaning Tower of Pisa and Mario said they are both way off.
Brooklyn T.Guy was upset about this but then, he decided to sell Mario a foosball table. Mario ask the price and he said that it is only $500 so Mario pay for it. The foosball table then was quickly deliver here. Mario ask how it deliver so fast and Brooklyn T.Guy said he has super fast shipping and then admit that the foosball was his. Mario got angry and Brooklyn T.Guy said he have to leave
Brooklyn T.Guy then went back to Jeffy and Jeffy ask if he got the WiFi power. Brooklyn T.Guy said sadly no and Jeffy wants a refund but Brooklyn T.Guy said he can buy a foosball table for only $300. Jeffy ask if it is fun and he said that it is really fun so Jeffy bought it. Jeffy and Mario then went up and simultaneously say “I JUST GOT A FOOSBALL TABLE”. Mario and Jeffy argue a little on how they got scam.
Jeffy then went back angry at not having the WiFi power but Bowser Junior then came telling Jeffy that he could’ve just use the WiFi of the area so Jeffy did and went back playing. Meanwhile, Black Yoshi got the paper and ask for the password. Mario said “A”and Black Yoshi wrote “Z”. Mario then said “B”and Black Yoshi wrote “Q” and the video ends.
