pinchbug
The pinchbug is a large black beetle with formidable jaws that Tom Sawyer brings to church in a percussion-cap box, where it escapes and causes a chaotic disruption during the sermon, becoming a memorable comic object that exposes the tension between boyish mischief and religious solemnity.
Identity and Introduction
The pinchbug is a large black beetle with formidable jaws, which Tom calls a "pinchbug." He keeps it in a percussion-cap box, the same container that had previously held a tick he traded with Huckleberry Finn. The beetle first appears during the Sunday morning sermon at the village church, where Tom, restless and bored, retrieves it from his pocket as a diversion from the minister's dry argument about fire and brimstone. The beetle's first action is to take Tom by the finger with its jaws, causing a natural fillip that sends the beetle floundering into the aisle, where it lands on its back, working its helpless legs, unable to turn over.
The Church Disruption
The pinchbug becomes the center of attention for other parishioners uninterested in the sermon, who eye it for relief. A vagrant poodle dog, sad at heart and lazy with the summer softness, spies the beetle and begins to play with it. The dog sniffs at it from a safe distance, grows bolder, and makes gingerly snatches, eventually subsiding to his stomach with the beetle between his paws. When the dog's chin descends and touches the enemy, the beetle seizes it, causing a sharp yelp and a flirt of the dog's head that sends the beetle falling a couple of yards away, landing on its back once more. The neighboring spectators shake with gentle inward joy, several faces go behind fans and handkerchiefs, and Tom is entirely happy. The dog, feeling resentment and a craving for revenge, continues a wary attack, jumping at the beetle from every point of a circle, but grows tired again, and eventually sits down on the beetle. This produces a wild yelp of agony, and the dog goes sailing up the aisle, crossing the house in front of the altar, flying down the other aisle, and clamoring up the home-stretch, his anguish growing with his progress until he becomes a woolly comet moving with the gleam and speed of light. The frantic sufferer finally springs into his master's lap, who flings it out of the window, and the voice of distress quickly thins away and dies in the distance.
Consequences and Significance
By this time the whole church is red-faced and suffocating with suppressed laughter, and the sermon has come to a dead standstill. When the discourse is resumed, it goes lame and halting, all possibility of impressiveness at an end, as even the gravest sentiments are constantly received with a smothered burst of unholy mirth. The pinchbug episode provides a genuine relief to the whole congregation when the ordeal is over and the benediction pronounced. Tom goes home quite cheerful, thinking to himself that there is some satisfaction about divine service when there is a bit of variety in it. His only marring thought is that he is willing the dog should play with his pinchbug, but he does not think it upright in the dog to carry it off. The pinchbug thus functions as a comic object that disrupts the solemnity of religious ritual, revealing the underlying tension between the natural impulses of boyhood and the constraints of adult authority and piety.
