I insisted on including tears in this article, but it's very hard to find a good use of them in films. The only movie I could come up with that had a unique use for tears is Cry Baby. Real-life prison inmate Amy Locane gives us a scene where she's, ironically, crying about Johnny Depp being placed in prison. She catches her tears in a jar and at the end of the scene drinks them down. Eeeewwww!
