West Side Story - I Feel Pretty 

While the "I Feel Pretty" scene in West Side Story is exuberant and happy, it's not as strong or intense as some of the other scenes in WSS, but it, too, has contributed a great deal to this great movie/musical classic just the same. Without various types of scenes/songs/characters to balance things out, West Side Story definitely would NOT be the great golden-oldie-but-goody keeper of a movie/musical classic that it is!
