[quote name='trytej']Nothing bad has ever happened to me. [/QUOTE]
That was me until I punched the stairs at our house. I got way too pissed off at my sister, so I right hooked, downward, onto the stairs. I'm not sure what it did, but it seemed to push my pinky bones back a bit as the knuckle is a centimeter farther behind the others. Hurt like hell until the next day, but no ill effects except I can't move my pinky around quite as much as the other.
