Ululation appears in many films set in the Middle East, such as Lawrence of Arabia and The Battle of Algiers and Lion of the Desert. Sometimes it is depicted as a battle cry, for example in Xena: Warrior Princess. Even the animated feature G.I. Joe: The Movie featured the ululation "Cobra-la-la-la-la-la". It appears as comic relief in The Simpsons episodes "The Last Temptation of Homer" and "Midnight Rx"; as well as on Family Guy in the episode "E. Peterbus Unum" where Stewie is curious about the sound Achmed "makes when you're about to assassinate an infidel". Further, Peter learns how to do this in "Turban Cowboy". In the film Get Him to the Greek, during the threesome scene, Russell Brand "ululates" the girl. The word also appears in the book Lord of the Flies[29] as a way in which Sam and Eric could warn the other members of Jack's tribe of the coming beast or other intruders. The word ululation is used in H. G. Wells's War of the Worlds to describe a sound that the Martians make during battle.
