Yes, you would know firsthand about the dogs/carpet spots. If I were clever enough to have thought of this graph idea, I think I'd be able to come up with one involving freshly-changed sheets being the ones most likely to get peed on in the night by continence-challenged small children.

I think I must have mentioned Daddy's spectacular tonsil-spot removal surgery before, but he's used his x-acto for numerous lesser procedures, most of which involved unwanted skin growths, splinters, cactus spines or ticks.

And you know, the swivel-headed x-acto is a wonderful tool, but so exacting in its swivelability that I find that I've got TOO much control, you know? In the hands of a virtuoso, though, it would work wonders.
