Jean-Ralphio Saperstein is a fictional character played by Ben Schwartz in the American comedy television series Parks and Recreation. He is the cocky friend of Tom Haverford and, like Tom, sees himself as a pickup artist and "baller", although he is looked upon with contempt by most people around him except Tom. Ron Swanson happily invests in Tom's "Rent-A-Swag" venture when he learns that for once Jean-Ralphio is not involved. He tries to dress stylishly, makes up and raps spontaneous rhymes but usually fails due to adding an extraneous word after the rhyme, and often speaks in slang terms, such as variations of the suffix -izzle as popularized by American rapper Snoop Dogg. For example, while comforting Tom at one point, Jean-Ralphio encourages him to "Turn that frizown upside-dizzity."
