Old wives tales anyone?

Have any of you used any and them actually be true?! I've seen so many things on the internet that actually contradict one another such as, "if it's a boy, you will crave sweets, and a girl, you will crave salty/sour" then on another page I read the opposite, "if it's a boy you will crave salty/sour, and a girl sweets and juice." It's horrible!
