Title: The Class of '89 Plot: Mary excitedly informs the students that she can arrange for Run DMC to perform at their prom, but there's a catch—their budget falls short of the $5,000 needed. In a bid to raise the funds, Dylan invests their money in stocks, but the gamble fails miserably, leaving them broke and unable to host the prom at a hotel. As a result, the event is relocated to the outdoor space of 227, disappointing the students. Determined to make it work, Mary and Dylan dress as rappers and manage to persuade Run DMC to join the celebration, saving the night.
