When did you last injure yourself and what were you doing?

It was a do or die attempt to open a can of pineapple with a flip top. The flip top key broke off. I decided I was going to open that can no matter what...and now I have to live with the what.

I injured my left hand pretty badly doing it. I developed a trigger finger and a ganglion on my wrist from the attempt. The trigger finger was repaired, and I will be looking into surgery for the ganglion sometime this year.
