There has been a research study done on the memorability of movie quotes. You can take the test here to experience just how they conducted their research. Below is the abstract from the study. I included a sweet movie quote from one of my favorite Zac Efron movies as an example. P.S.- That’s not english

“Understanding the ways in which information achieves widespread public awareness is a research question of significant interest.  We consider whether, and how, the way in which the information is phrased —- the choice of words and sentence structure —- can affect this process.  To this end, we develop an analysis framework and build a corpus of movie quotes, annotated with memorability information, in which we are able to control for both the speaker and the setting of the quotes.  We find significant differences between memorable and non-memorable quotes in several key dimensions.  One is lexical distinctiveness: in aggregate, memorable quotes use less common word choices, but at the same time are built upon a scaffolding of common syntactic patterns; another is that memorable quotes tend to be more general in ways that make them easy to apply in new contexts.  We also show how the concept of “memorable language” can be extended across domains.

UPDATE: The Economist has written an article explaining some of the findings.
