I walk out on court and start warming up when I feel a bug land on my back. I turn around but can't see very far past my shoulder. I put my arm back there to swipe him off, but there is no bug. A bird just took a dump on me and I smeared it across my back. I changed shirts and wiped off my hands and resumed playing like total shizz. Lesson learned. When a bird takes a dump on you; call it a day.
