Ever wondered just how painful the classic "Wood splinter under the fingernail" torture really is?

Well, as of yesterday, I can tell you that you can jab a 2mm wide piece of wood, about 1 cm deep, right under your thumbnail, and hardly feel a thing!

That is, if you do it fast enough. You have to do it really, really, really, fast. Like instantly.

Do it slow and it will hurt like hell.

It's also best if you have absolutely no idea that its going to happen. The anticipation will make it hurt much more.

So there. Now you know.

And so do I.
