This may be one the most underrated comedies ever made. This movie has made me laugh out loud each of the many times I have seen it. One of the things that makes it really special, however, is that this would be a good movie even if it never had a funny line. The reason is that it is simply a great story. The plot is full of twists and turns, and leaves you surprised at the end. This alone would make this movie a "7." Add the numerous laughs, and this movie becomes an undenible "10."
