What I like are his spaghetti arms, incipient gut, and his effete manner. I like the way he tweaks his hair like a teenage girl in between points. It's important I think for a player to be immaculately groomed just in case he has to rush of to a posh social gathering mid-game.
I love his awe shucks innocent yokel from the Swiss Alps routine too. It's adorable - even when it falls off script and lets his inner darkness seep through.
What I like about tennis are the brutal warriors, those intense souls that simply cannot hide their passion as they scream, sweat, and grunt like damn near every other big, professional, Western culture sport. Such examples of raw talent chase down everything, not with superior movement or balance, but instead while simply sprinting, even while bent over, to arm shots back thanks to the aid of modern technology's "advancement" of the racket. Said technology will, in several years time, hopefully lead to the possibility of passing shots that are hit from outside of the stadium while on one's ass with a handful of ribs... aka by those in full body paint "tailgating" the eventual matchup between buff grinder #1 and buff grinder #2 on yet another slow hardcourt. Then tennis will become like every other sport, complete with Michael Phelps-esque tards screaming during points and talking about how "sick" a particular 80 stroke rally was. Maybe they'll even invent halftimes so they can wheel out one of those machines that shoots hot dogs into the stands.
Until then, we'll just have to deal with the sloppy variety we've been dealt, which includes fat, thin-armed, nerdy looking dweebs with corny laughs, girly hair, too much money, fat girlfriends, whiny spoiled excuses, and no visible sign of gym-physique athleticism to speak of. Never mind how these kinds of athletes, and I use the term loosely, play tennis; it doesn't look "good" and it isn't "cool." Real tennis, please evolve quickly and take over for good! Federer and the like, please quit!
