The Upper Crust
I had a friend who married this girl who was determined to "reform" him. In no time at all, she had him stopped from smoking, drinking and staying out all hours. She introduced him to the finer things of life, like art and music. She taught him to dress well and to master the rules of etiquette. She got him a top, well paying job.
One morning he took a look around and decided she wasn't good enough for him and left her.
