A surgery that would produce a working human tail...?

Now, I've heard of people asking this before, but I have to know, especially if anyone is a doctor. Would it be possible to, by some way, add a tail to the existing spine of a human, in essence simply extending the spine by a large amount? I assume that there is no surgery for this, since it is aesthetic at best. Then again, I would be thrilled to have a working tail. Now, my question is 'would it be possible' I'm just trying to figure that out, if so, then I could figure out if anyone would be willing to do it.... though I doubt it. Of course, there is the issue of attaching nerve tissue to the new spinal extension, which I geuss could be obtained from a chimpanzee cadaver's tail, or maybe the spine of a human cadaver, but, that would have the wrong nerve structure to properly serve as a tail, I assume, and if it did, the responses from the brain would likely be incorrect. Well, if anyone can answer this, then please give me an answer. I am very curios to see if this is even plausible

[Update, to respond to people's answers] What I meant, exactly, was, to find some way to extend the spine past the tail bone, by either A-) Taking a tail from a chimpanzee (closest relative to human with an articulated tail) cadaver and somehow appending it to the end of a human spine [this seems impossible] or B-) Taking the articulated spine from a human and appending it to the end of one's spine. [this seems more plausible, but then the tail would move uncomfortably at best] And just as well, our ancestors had tails, and considering that brainpower is used as it's needed, it may be very likely that, once one has a tail, he would 'remember' how to use it. catch my drift? And to what someone else said about why would you want it.... Of course my reply is... Tails are awesome! And, also, I could pick up stuff... To a great extent, it would serve as a third arm.

Yeah, I realize that the spinal cord ends, what I was thinking, was, and stop me if I start sounding outrageous, actually taking out a couple of the vertebra at the end of the spin, and taking a few vertebra of the top of the soon-to-be attached secondary spinal cord, and then somehow connecting the nerves and fusing the two together... (I don't mean to literally 'fuse' the bones together, but if that would be the only way, then I don't need to bend at my back-end much anyway, lol)

Possible or not; it would be akin to creating a new human with different physiological features.

I wonder if any one has seen that program "Vanity INSANITY".

God Help US :)
