Fuzz

Navel fuzz, belly-button fluff - whetever you want to call it. "Isn't it weird how it's always blue?" you hear the less imaginative and the dim-witted folk say.

Well, I would have thought that anyone with eyes and more than three brain cells could tell that it's not always blue, it's not the colour of your socks, and it doesn't depend on what day of the week it is.

Get over it.
