Make sure you have a really good (maybe even industrial strength) plunger in your possession during your partners pregnancy. This is especially true if she's taking those prenatal vitamins (which smell like vanilla), they'll really make her constipated. After at least a week of not taking a dump, it will be as if she's giving birth out of her backside. It's unlike anything you, or even that poor toilet has ever seen. If your lucky, she'll be too nauseous to plunge it herself and leave a surprise for you to take care of. Awesome.
