I've moved black lump charcoal and burned the hell out my fingers, cut the tip of my thumb off with a meat slicer (who needs the guide?). But probably what probably caused the most pain was when I popped a small ghost pepper that I had smoked into my mouth. Who knew smoking didn't take the heat out? Almost had to go to the emergency room on that one. Hot hiccups are very painful. Milk and saltines worked a little. Then I had to experience the pain the next day if you know what I mean.
