How dare you!
Here's my take:
Poobs has illustrated to to the unwashed masses how the game of tennis really should be played. There's the old tennis quote: "if it looks like you're trying hard, you're not doing it right." Well that's the case here: what we incorrectly interpret as sloth-like movement is actually the master exhibiting a silky smoothness which is the hallmark of any
fully-rounded, perfectly developed game.
In short, the uber-Poober (like all true greats of the game) make it "look easy."
Notice his out-classed opponent flailing away like a man in total darknes, spraying shots all over the place.....while Poobs is a picture of composure.....total serenity in a robust, athletic package.
