Sid is the obedient, well-behaved counterweight to Tom in Aunt Polly's household, and he knows exactly how to profit from his brother's failures. He calls attention to Tom's black thread and lands him in trouble, then takes the punishment for it in a volley of dirt clods that Tom launches before fleeing over the fence.
