Pazuzu

Pazuzu is a demon of the south-west winds.

History
Homer ordered an idol of Pazuzu from Iraq, thinking it was pizza. He gave it to Maggie and the idol possessed her. Pazuzu, in Maggie's body, decided nobody could leave the house alive, whist the Simpsons were having a party. Pazuzu then started murdering the guests.

Ned Flanders suggested that they should give Maggie an exorcism and they tied her to her crib using Bible ribbons. Pazuzu then killed Ned. Eventually, an Irish priest arrived and started the exorcism, telling Homer and Marge to cut her loose. He held up a cross and said "devil be out" three times, causing Pazuzu to leave Maggie. Pazuzu then possessed Bart's body, but wanted to get out as Bart was the darkest soul he had ever seen. Bart then told Pazuzu to give him horns, which Bart used to stick through Homer.
