A man is sitting down in front of the fire place and is reading the Bible. His wife comes in and looks down at him and says, "Why do you always sit there and read that thing, what does it help?" He looks up at her and says, "I read it because it has an answer and examples of everything."
After giving her husband a weird look, she says, "In that case I want you to find an example of where a woman had PMS in the Bible, and I'll even give you until tomorrow." So, he goes along with the deal.
She comes back out the next day and says, "So, did you find it?" He slyly smile and says, "Yeah, when Joseph was taking Mary to Bethlehem, she was riding his ass the whole way there!"
