While taking a break at a restaurant, Ash and Co. hear that Professor Oak and DJ Mary would be arriving in town. Team Rocket sees an opportunity in this and disguises themselves. With Jessie as DJ Mary, James as Professor Oak, and Meowth and Wobbuffet as their manager, things go very well for them until the real Professor Oak and Mary show up. Unable to tell which is which, Misty suggests a contest with things only the REAL Professor Oak would know. Which Oak is more knowledgeable?
