They use direct quotes from the show. A fan character added into the show named Derpy had only one line, which was "I just don't know what went wrong", and when one other character starts going crazy due to a report she hasn't completed, starts insanely telling herself "Clock is ticking, Twilight. Clock is ticking!"
I know these sound pretty generic and like they could be coincidences, but they are said in a way that makes them pretty memorable quotes.
