Remember George Costanza's wallet that made him sit on a tilt? Jon doesn't sit on a tilt but that's only because he doesn't store his morbidly obese wallet in his back pocket. He uses a front pocket instead. Like George, he claims he needs everything in it.
How 'bout those keys? I guess bishops are like janitors, they need a key to all the locks. But does he really need them all on a daily basis? That's a lot of extra weight to be carrying around.
But with the keys in one pocket and the wallet in the other, I suppose he feels quite balanced. Weighted, yes, but balanced.
