Jean-Ralphio is a young man who was first introduced in "The Set Up" as Tom's top choice to be Ron's assistant. His cocky personality is identical to Tom, which is why Tom liked him and why Ron hated him, denying him the job. Jean seemed very interested in April during his meeting with Ron. He has a sister named Mona-Lisa Saperstein, and their father is Dr. Saperstein.
In "Woman of the Year", Jean-Ralphio and Tom look for a co-investor so they could buy a share in the ownership of Pawnee's sickest nightclub, The Snakehole Lounge. His grandfather just passed away so Jean-Ralphio states that he is "flush with cash" but can only kick in $5000 when Tom needs $6000. When asked about his trust fund, Jean-Ralphio says that his parents had it amended so he could not touch it until he is 50, which he states will be a total waste since by then he'll be a billionaire living in Costa Rica "eating dolphins and hanging out with lady-singers." Jean-Ralphio reveals that he drives a pre-owned Acura Legend. Donna Meagle - the only person who attended Tom's investor presentation that was possibly interested in helping them out - immediately hated Jean-Ralphio upon meeting him and called off the deal, although she later bought three shares on her own. Despite all of his big talk and boasts, Jean-Ralphio actually works at Lady Foot Locker, as revealed by April Ludgate in "Woman of the Year".
He again appears in "The Master Plan" at April's party, where she makes out with him to make Andy jealous. Jean-Ralphio's favorite drink is Remy Martin. Andy also takes a disliking to Jean-Ralphio. He refers to Tom as "Big T." Ralphio once stayed outside of a house for five days believing it to be the house of the chick that he wanted "to drill".
In "Li'l Sebastian", Jean-Ralphio and Tom Haverford are trying to come up with investment ideas. Jean-Ralphio says he "made his money the old fashion way" by getting run over by a Lexus. Tom comes up with the idea that then becomes Entertainment 720.
