There are so many one-liners in this movie that THAT is reason enough to watch it.  This is one of the best "ensemble" casts ever and this movie will go down in history as a class act.  My daughters grew up with this and THEY love the movie as much as I do...we recite one-liners to each other all the time and it never fails to make us laugh.  I definitely get the same feeling from others which says a lot about the movie!
