Cornell researchers took short, memorable lines from around 1,000 movies and compared them against other lines of a similar length spoken by the same character at about the same point in the film. (They define memorable lines as those listed as such on the Internet Movie Database website, IMDB.com.)

They then asked individuals who had not seen the films to guess which of the two lines was the memorable one. On average, people chose correctly about 75 percent of the time, confirming the idea that the memorable features are inherent in the lines themselves and not the result of some other factor, such as the length of the lines or their location in the film
