I actually broke my laptop when I smacked a fist on it during last year's Wimbledon final.
I almost destroyed my hand during the Madrid final. When Nishikori couldn't hold his serve I was like "Fuck!" and hit the wall next to me with the power Tsonga hits his forehand. Kei would've so deserved to win that title.
And I always keep the remote controller on table after once almost throwing it to window.
