Sorry to hear that, man.

I'm really clumsy, boiled a couple of eggs, and somehow carelessly put the back of my hand on the cooker hob. The problem with doing that is that it takes a little time for the pain to kick in, and then to react to the pain by removing your hand, so I ended up with a stinging red burn that lasted a week, with skin falling off it.

So it turns out you can get hurt if you're NOT really careful also. :(
