--as in, things that do not occur in nature.
Or at least that are really, really, really rare.

Thomas made a blue poo.
That's right: blue. And we are not talking some sissy periwinkle or powder blue here--this was a completely different Benjamin Moore swatch card. Now don't get me wrong, it wasn't navy or even cobalt either, but definitely it was a blue with some gusto.

This didn't exactly come from nowhere. Over the previous couple of days Thomas had, in fact, just discovered blueberries. And I suppose eaten a few too many. But still: it was quite a shock.
