Got the tip of my right index finger nipped by a blue-throat trigger; not enough to break the skin even, but enough to let me know that was the next option!
Slashed open my right ring finger at work on a very sharp piece of glass when a group of kids came into the quiet building, and all dozen of them must have shrieked at once when they saw my hand in the tank. I jumped, startled, and slashed open the other hand. Didn't stop bleeding for nearly ten minutes...and since the glass was on a salt-crept lid...double ouch.
