because I'm feeling silly
This is good, because maybe you can shed some light on something that I believe falls under the general heading of Silly Design.
I am speaking of human toenails. As a member of the human species, I can't see any specific purpose to having toenails, except perhaps to annoy the Mrs by letting it go a little too long before cutting them. And that's another thing, why do the bloody things have to keep growing? If indeed they do have some useful purpose that I am so far unaware of, wouldn't it be more intelligent to design them to grow to the ideal length only, rather than have constant growth that requires regular trimming?
I'd say this combination of inconvenience with no practical purpose qualifies the toenail as an example of silly design. Though I guess I should mention that toenails do cause socks to wear out sooner than they normally would and thereby help to keep the sock industry in business, and I don't think anyone wants to see the sock market crash.
