12. Once in Love with Amy

Complete story — includes the ending

On the night of Amy's bowling league, the babysitter cancels on her. Eric, feeling responsible, decides to be mature and volunteers to babysit Cory and Morgan. In class, Mr. Feeny poses a math question, in which Cory and Minkus get wrong. However, Topanga finds the solution. Feeny explains that the answer to the question is not in fact a mathematical solution, and that it is the student's responsibility to figure out what the answer is. Feeling stumped, Shawn and Cory decide to test out Mr. Feeny's question on a Barbie doll and a toy car. Consequently, Minkus arrives at Cory's door on the edge of a nervous breakdown after his failed attempt at solving the problem. Later on, Cory finds out from Shawn that Amy's bowling league had ended nearly six weeks ago, causing Cory to worry. Cory, Shawn, and Eric open Amy's bag finding a cocktail dress. The brothers leave to follow Amy, leaving Shawn in charge of Morgan. Upon their arrival to the restaurant, Cory and Eric see their mother dancing with a mysterious figure. When they arrive home, Eric decides to tell Alan about what he saw. Then, however, Amy explains to the boys that she was the one dancing with Alan. She also explained that since they were busy parents with three children, they hadn't had time for each other, so she and Alan decided to add some mystery into their date. Back in the classroom, Feeny tells the class of Topanga's answer, revealing "the secret of life"— people change people, from which he learned from his mother. In the post-credits, Minkus is shown to be still stuck on trying to figure out the mathematical answer to Mr. Feeny's problem, and inadvertently discovers time-travel. However, he chooses to disregard it. Guest star: Danielle Fishel as Topanga
