Ninja vs Ahole co-worker

One time, I scared the living crap out of one of my co-workers accidentally. He was kind of a jerk. One day he was trying to get me to go down the cage and get something for him, or do some work down there… I can’t remember. Anyway, I was looking down at my computer because I was (surprise!) working on something. I didn’t want to stop what I was doing to go down the cage. I guess he got frustrated that I wasn’t paying enough attention to him, so he threw the cage keys at my head. The keys to the cage were on a heavy key chain with 10 or 12 other keys and fobs. It was a dick thing to do. I saw the keys coming at me in my peripheral vision, and without even looking up from the terminal, my left hand shot over and caught the keys about an inch away from my right eye. I held the keys where I caught them for perhaps 30 seconds while glaring at my co-worker over the top of my hand. You should have seen him. His face went pale. His eyes went wide. Who knows what was going through his mind. I must have seemed like a ninja in that moment. I have no idea how I managed to catch those keys. I am not a ninja. I am not even left-handed. But, after that Mr. Asshole T. Co-worker was quite a bit more respectful around me.
