Homer becomes a costumed vigilante who uses pies for weapons after witnessing Lisa get humiliated at a competition at the state fair.
After the Texan millionaire mocks Lisa's entry at the fair Homer,disguised in a mask and cape,throws a pie in his face and becomes an avenging super-hero,putting pies in the face of those who deserve to be punished. However he is unmasked by Burns who threatens to expose him unless he pies the visiting Dalai Lama and has to be helped over his crisis of conscience by Lisa.—don @ minifie-1
