Inner Beauty
Once upon a time, a man felt lonely and wanted a wife to share his life with, so he built a robotic wife out of wires and tubes, nick-naks and bric-a-brac. They fell in love and were very happy together for many, many years. But the wife began to wonder why the man could never pick up his dirty socks and pants up off the floor, no matter how many times she asked him to. One day, after picking up yet more of his dirty underwear, she lost blew a gasket and in a fit of rage she threw the man straight through the wall of their little house in the forest. The man fell, down, down, down, until he hit the ground and died. Saddened by what she had done, the wife cried unending tears of sorrow, until she rusted up, sat frozen by the side of the grave of her dead husband.
Or
Once upon a time, a man felt lonely and wished for a wife, he wished and wished but his dream never came true. One day a wizened old lady appeared at his door asking for some food. Although she was hideously ugly, (I mean REALLY, TRULY repulsive), he took pity on her and shared his meal. The old lady revealed she was in fact a witch and would reward the man for his generosity. After telling her of his dream the witch turned a nearby rabbit into a beautiful woman, who fell in love with the man and they quickly married. However the wife remained some traits of her former life, and the man soon died, (naked), of exhaustion. The wife cried at his funeral whilst eating a carrot, before smiling at a lonely gravedigger, who also died just a few blissful days later.
(BTW - These are in an original Grimm style, so there is no happy ending, just lessons to be learned - bonus points for guessing correctly, hint, the 2nd one is well known)
