Napoleon Dynamite was one of the strangest films of the last decade. With a tiny budget, this independent film was also done in a very precarious equipment, almost like a home movie, but it ended up raising millions of dollars. Even won an MTV Movie Award for best film, although it never was nominated for an Oscar or a Golden Globe.
Written and directed by Jared Hess, in Napolean Dynamite the quotes are the movie, and are so great that there are several websites that collect them, and many have become classics, like the line "Gosh," the one that the main character constantly repeated. And that's why almost the majority of the lines can be found on the Internet, and these are some of the links that have it: http://quotations.about.com/od/funnymovieandtvquotes/a/dynamite_topten.htm

Even there is a Napoleon Dynamite soundboard on the Internet, as you can find on this page: http://www.collegeslackers.com/soundboard/napoleon_dynamite, which contains phrases of the three main characters.
Also the Napolean Dynamite soundtrack of the film was very famous, and the theme of Jamiroquai Canned Heat was part of Napoleon Dynamite, a song that not match at all with the characters but in a way it is so perfect that ends up being another funny aspect of the movie.
