A young man finds the woman of his dreams and asks her to marry him. He tells his mother he wants her to meet his fiance, but he wants to make a bit of a game out of it. He says he'll bring the girl over with two other women and see if his mother can guess which is the one he wants to marry. His mother agrees to the game.
That night, he shows up at his mother's house with three beautiful young ladies. They all sit down on the couch, and everyone has a wonderful evening talking and getting to know each other.
At the end of the evening, the young man asks his mother, 'OK, Mom, which one is the woman I want to marry?'
Without any hesitation at all, his mother replies, 'The one in the middle.'
The young man is astounded. 'How in the world did you figure it out?'
'Easy,' she says. 'I don't like her.'
