Homer the Vigilante

Homer, Moe, the Sea Captain and Skinner can't seem to handle guns safely to save their own lives. Ignoring Homer looking right down the barrel of his own gun, when Marge expresses her reservations, they start accidentally discharging their weapons all over the place as Homer attempts to reassure her. Somehow, even Bart gets hold of one and does the same thing.
