Will the Real Oak Please Stand Up?

DJ Mary is known for her celebrity interviews and radio shows, which are broadcast in both the Kanto and Johto regions. One of her frequent guests is Professor Oak, with whom she is good friends. She herself has also achieved a certain level of celebrity status, as evidenced by her own fan club. Jessie and James want to experience the perks of celebrity life for themselves, so they disguise themselves as DJ Mary and Professor Oak. With the help of Nurse Joy and Ash, a quiz duel is organized between the two couples to identify the real duo. To avoid looking foolish in the quiz, Jessie sneaks into DJ Mary's recording studio to gather information about the real Mary. Suddenly, the real Professor Oak appears, demanding his daily dose of sex. To avoid being exposed, Jessie has no choice but to go along with it.
