PMS
A preacher was telling his congregation that anything they could think of, old or new, was discussed somewhere in the Bible and that the entirety of the human experience could be found there.
After the service, he was approached by a woman who said "Preacher, I don't believe the Bible mentions PMS."
The preacher replied that he was sure it must be there somewhere and that he would look for it.
The following week after the service, the preacher called the woman aside and showed her a passage which read, "And Mary rode Joseph's ass all the way to Bethlehem."
