What's the most recent way you stupidly managed to accidentally hurt yourself?

Not a serious one, but it hurt like a bitch.

Coworker was cleaning the donut case for the day, and left the dishes beside the sink. I decided to be nice and get them soaking, so I grab all the wire racks.

One slipped, and while I was trying to catch it, I somehow pinched my thumb right behind the nail between two others. I had to take a moment in the back office after that.
