I was making hummous with one of those hand held blenders. In the beginning the chick peas clag up the blades and have to be dug out until the hummous gets wetter. I was digging the chickpeas out when I reflexively squeezed the blender (stupidly still plugged in) and blended the entire first joint of the underside of my pointer finger. Thank god it wasn't the nail, that would have been terrible. As it was the finger flesh was in huge chunks though still connected. I bound it all up tight and it eventually healed though it is still scarred and a bit lumpy and also alternately numb and too-sensitive.
That was really beyond stupid.
