I keep the rubber dome keyboard at work on the desk just behind my WASD.
One day I picked up my bottle of diet coke and missed my mouth a whole lot. Laughed when I saw it on the rubber dome. Froze when I saw it on the F keys of my WASD. A small break and a lot of tissue paper later, it was sorted.
Then there was the time at i52 this summer, where I had my PC on the desk, next to my V60 mini playing a game of Dota... I swear Bloodcyka makes you mad... Anyway, I had a bottle of water open on the desk, and I did something stupid and slammed my fist down on the table. Bottle and water went everywhere, keyboard, desk, papers, lap... underneath my PC...
That was probably the worst. I pretty much stopped playing dota after that.
