The episode starts off with Jeffy screaming for help in a room. Mario is trying to ignore this, before Rosalina stops by and goes to the bathroom.
She finds Jeffy and demands Mario to explain why Jeffy was locked in the bathroom for hours. Mario revealed that he didn't know Jeffy was locked in the bathroom and that he thought Jeffy's screaming was from the neighbors or a lawnmower. Rosalina decides that Jeffy should have a cellphone in case of an emergency, but Mario disagrees and says that Jeffy would be too irresponsible.
Mario then gets an idea and buys a walkie-talkie. After explaining what a walkie-talkie is to Jeffy, he goes to his room and continuously annoys Mario by making noises. Rosalina and Mario decided that was a bad idea and get Jeffy a flip phone.
When Mario mentions that he can put it up to his ears and mouth, Jeffy snaps the phone in two. Mario and Rosalina then go back to the store to get Jeffy an iPhone. Jeffy learns his favorite contacts on his phone. Then, he goes to his room and continuously messages and calls Mario, whilst sending pictures to Rosalina of him drinking bleach and his excretion.
Reluctantly, Mario responds to Jeffy's phone call and tells him to play games on his iPhone. Jeffy accepts that Mario does not want to talk to him, so he prank calls various people. Then, he calls a prostitute, in Mario's name, to come to his apartment. The prostitute shows up and explains to Mario why she is here. Rosalina becomes furious and repeatedly spanks Mario for cheating on her.
