The video starts with Cody kissing Ken at his desk in school. He turns to see Junior, Joseph and Toad looking at him. He exclaims that it's Valentines Day and says he thinks they haven't seen love before. Junior and Joseph get surprised at the fact it's Valentines Day. Junior gets upset at the fact that he doesn't have a Valentine and asks Cody who his Valentine is.
Cody replies by saying it's obviously Ken. Junior then asks Joseph who his Valentine was and Joseph said that it was his mom. Junior was surprised since Joseph's mom was dead. Junior then asks Toad who his Valentine was and Toad said that it was his rap music. Jackie Chu explained to the class that there would not be any kissing or hand holding and then said that there was a new student named Britknee.
Junior who thinks she is hot decides to go ask her for a pencil. When he does she goes ew as well as telling Jackie Chu on Junior so Jackie Chu tells Junior to sit down. Junior thinks about writing her a note. When he does she gives him a note with the word ew on it. Cody then gives Junior a love potion so Junior goes to inject Britknee while Jeffy walks in saying, "I'm here f*ckers!" Jackie Chu gets upset at Jeffy while Jeffy said he got his pee pee stuck in Cheerios. Junior injects Britknee and then walks away from her which Cody tells him to get in front of her. But Junior screws up by letting her fall in love with Jeffy.
Jeffy gets home telling Mario that he got a girlfriend. Mario thought he should meet her so Jeffy has her over and tells Mario that he wants to eat her butt. Mario says no but then Jeffy has her wear a diaper and spank it.
Cody goes to the house to tell Junior that the love potion would let Britknee turn into a dragon so she does and Junior injects her and Britknee breaks up with Jeffy. Then Jeffy says "hoes will be hoes." Mario questions Jeffy for not being upset and Jeffy says "No Daddy I hit her in the face and send her to bed". So Mario tells Jeffy that he should meet the girl next time he dates someone ending the video.
