This Friday, Nicholas Stoller's "The Five-Year Engagement" hits theaters. The rom-com stars Jason Segel and Emily Blunt as a doomed couple with an ever-lengthening walk down the aisle.

Thanks to the comedic gifts of Segel and Blunt, along with their co-stars, Alison Brie and Chris Pratt, the film is a general joy to watch. However, you may find yourself aching for the credits: It's long. Really long. Over two hours long.

This had to be a romantic comedy blunder, right? (The film's length is no stranger to producer Judd Apatow, however, whose movies tend to fall around the two-hour mark.)

So! In honor of "The Five-Year Engagement," we've gathered a couple of your favorite flicks to serve as a guide to the DOs and DON'Ts of rom-coms. Hey, those who can't do, teach, right?
