Graves' Achilles' Heel

So I was in a game just now where I was Graves. I got a six kill streak early on, and as the game went on we got into a teamfight in midlane. My mouse started acting screwy, halting in one position while I tried to reposition my character. I couldn't, and I died. I checked the underside of the mouse, and I found a hair that got stuck right next to the laser!

Can you imagine!? The mighty and indomitable Graves was taken down BY A SINGLE HAIR!
