PJ Duncan (Jason Dolley) is the eldest Duncan sibling. He and Teddy often fight, although they care about each other, and he usually gets along well with his younger brother Gabe. He often appears awkward, somewhat careless, and childish, but on numerous occasions has been known to be resourceful, creative, and intelligent. He has also been shown to be a good cook, and Bob once tricked Amy (who is n't a very good cook) into working later so that PJ would cook. He and his best friend Emmett have their own band entitled "PJ and the Vibe ''. PJ occasionally uses his younger sister Charlie for his personal gain, like when he uses her to make big tips while working for Kwikki Chikki by saying that his mother was in the hospital when she actually worked there (customers just assumed she was ill). He dated Teddy 's friend Skyler, who has his type of scatterbrain, but they broke up in "PJ in the City '', when Skyler had to move to New York City because of her father 's new job. He was originally intended to be named after his great - grandfather, Patrick John, but Bob was nervous as he was writing on his birth certificate, resulting in the legal name of "Potty John '' instead of the intended "Patty John ''. Despite Bob trying to correct this in the season two episode "Can You Keep a Secret? '', he accidentally changed the intended name to "PP Duncan ''. It is revealed in the "Special Delivery '' episode that his middle name is Darth. In season three, PJ moves into an apartment shared with Emmett, but is still in the Duncan house a lot. In the season - four episode "Good Luck Jessie: NYC Christmas '' he gets back together with Skyler, who will be attending college in Denver. In the final episode, PJ has graduated cooking school, buys a food truck, hires Emmett to work for him, and makes Bob his business partner. Also in the last episode, PJ finds Skyler in Denver, who forgot to mention she moved back to Denver to go to college.
