Looking at incredible table tennis trick shots on YouTube and thinking I've not been so elated by physics and trajectories since the Tenth Doctor casually picked up a tennis racquet and took out the hitherto undefeated General Staal of the Sontaran Battle Fleet with a nonchalant flick of his racquet and a well-aimed tennis ball that ricocheted into the probic vent at the back of the Sontaran's neck. What a thing of athleticism, precision and style, the Doctor and the player both.
