I suppose some guys have heard Evolutionists say things like "if we didn't evolve from monkeys, why do we have a tail bone?"

Now, there is one answer, but Kent Hovind and Keaton Halley handle it in stylistically different ways.

Kent Hovind

(from memory):

If you think you don't need your tail bone, I'll pay for you to have it removed.

[+ a few hints about what can happen if you do, involving, I think "I don't advise you to do so"]

Keaton Halley

(citing copypaste-wise)

Some evolutionists have pointed out that there are cases in which a damaged or diseased coccyx has been surgically removed, proving that the coccyx is not essential. But so what? Having a purpose and being essential are not the same thing. The fact that one can live with the loss of a pinky toe, for example, does not demonstrate that it has no function. For that matter, one can live without arms, legs, hair, teeth, and half of a brain—yet all of these parts are clearly operative in a normal, healthy body. If they are missing, either other body parts must compensate, or the body will suffer from the loss.

The same is true regarding the coccyx. This is obvious from the fact that removal of the coccyx means severing those muscles, tendons, and ligaments to which it is attached (and perhaps re-attaching them elsewhere). But personal testimonies are also available online that indicate recovery from a coccygectomy can be difficult—including pain when sitting or moving, not to mention bathroom complications.

[The last point was included in Kent Hovind's hints.]

Keaton Halley's article can be enjoyed in extenso, it is very informative as the sample can make you see, on todays blog post of CMI:

I am glad that ma, as med student and back then part time "intern" (if that is the term for a Medicinae Candidatus or Candidata who is working as physician under others at a hospital, before getting Legitimation or even Med. Dr.), was also a creationist, aware that tonsils and appendix are not useless junk.

This, the article linked to, at least for appendix:

Since not a physician myself, what about CMI getting one to write about tonsils?/HGL

PS, here is another goodie for those enjoying biological hard science and finding too little of that over here (except the repeated item of Chromosome Numbers, a k a Karyotypes):
