Near the end of this episode when Cory encourages his students to "Dream. Try. Do good.", this is a direct reference to Mr. Feeny's parting words to his favorite students in the final episode of "Boy Meets World". Marly says "Don't you mean 'do well'?" to Mr. Matthews just like Topanga says to Mr. Feeny, and that is why Cory makes reference to history repeating itself.
