Being a ball boy in tennis is like being a waiter. If you do your job right, no one should really notice you.

This kid was working as a ball boy at the Barcelona Open when he tripped after getting some balls (he did suck them like a Gold Glove-winning shortstop) and ran smack into a wall, while a live crowd and television audience looked on.

That's a tough spot. It's the equivalent of dropping your tray in the middle of the school cafeteria -- everyone know what you did and there's no way to squirm out of it.

We give props to the kid here, though, because he soldiers on like nothing happened and simply stands upright like he's a guard at Buckingham Palace. He didn't shrink in the moment, even though he goofed by tripping over his own feet.
