About Jonathan[]
Jonathan is bright, sparky kid who is one of Mork's circle of kids in the Day Care Center. With a personality like he has it is no surprise that Sugar Ray Leonard is his hero. Jonathan is forthright and quite mature in his behaviour, offering his opinion to Mork without hesitation, and commiserating with him to the point that Mork almost feels like he's the one being patronised.
