By "alien," we're not talking about the guys you picked up at The Home Depot to help deliver the baby. We mean the "Sigourney- Weaver-fighting" kind (whose birth scene prepares you for the gore, if not the pooping).
As it turns out, babies' heads are soft, and don't become hard until months or years after they're born. This explains why you don't usually see them at college parties, crushing beer cans with their foreheads. Well, this and the fact that they weren't invited since they cry all the time, and puke all over the place before the drinking even begins.
Either way, having a soft skull comes in handy when you're trying to be born without killing your mother in the process. Unfortunately, their heads don't instantly regain their shape once they pop out. It takes a day or two of looking like a butt plug before you can take your little-one hat shopping.
If the doctor feels that your baby is at risk of anything (juvenile diabetes, low birth-weight, high birth-weight, medium birth-weight), or if he just feels that he can charge you more, he may elect to hook up a fetal monitor. That doesn't sound so bad, right? Well, that is because "fetal monitor" is just a nice way of saying "a twisted metal thingy with wires coming out of it that we're going to screw right into your baby's freaking unborn head."
Now, the fetal monitor itself isn't all that scary looking. But the fact that they jam this thing into the babies soft spot while it is still in the womb, and they stick it in there far enough that it stays inside the skull until after the baby is born, will bring back vivid memories of that baby getting hooked up to the Matrix in the first movie.
"OK, now, nurse, hand me my power drill, please."
Couple that with the fact that a baby's heart slows way down during every contraction, which sets off a little alarm on the monitor similar to the one that goes off when a patient flatlines on Scrubs, and you may find that you have shit your pants before the whole thing is over. Don't feel bad though. Like we said, there is a lot of pooping going on at this point, so if you do let one slide, just motion towards the mother when she isn't looking, and plug your nose as if to say, "Yeah, I smell it too. It was her."
Births are really expensive. Even a complication-free birth is likely to cost upwards of $10,000 and if your baby comes out and so much as sneezes in the delivery room, this number is likely to start rolling up like a pinball score. Sure, maybe you're one of those fancy-pants families with this New Age "health insurance." But tack on the cost of the car seats, baby clothes, toys, diapers, bottles, play pens and aforementioned placenta memory-erasing Belgian ale, and you can plan on having spent more than your burger-flipping ass makes in a year before you even leave the hospital.
"Is it really worth it?"
So basically it's you letting another man touch your wife's private parts, then writing him a check. Then you watch him speed away in a Lexus on his way to a round of golf being played at some country club that you are now too poor to even clean the toilets of, let alone get a tee-time at. OK, we're probably taking it too far. We're sure they'd let you clean their toilets.
