I remember as a little girl going into a five and dime store in my home town and not knowing what a stapler did. I put my finger in it and pressed. OMGosh, I didn't know how much a finger could bleed...LOL I am also the queen at sticking myself in the finger while hand sewing. Sometimes I think I must buy the sharpest needles they make. I have heard about people putting a sewing machine needle through their fingernail and finger. OUCH. Glad damage was minimal but it probably didn't feel that way.
