Chief Clarence "Clancy" Wiggum is a fictional character from the animated television series The Simpsons, voiced by Hank Azaria. He is the chief of police in the show's setting of Springfield. He is the father of Ralph Wiggum and the husband of Sarah Wiggum. The character's comedic value relies heavily on his incompetence and irresponsibility as a police officer, and his laziness and gluttony. Chief Wiggum's more responsible fellow officers Eddie and Lou play the straight men to his shenanigans.
Chief Wiggum was born in Ireland and moved to Springfield at an early age. Per the episode Raging Abe Simpson and His Grumbling Grandson in "The Curse of the Flying Hellfish", Wiggum's father, Iggy, served in Abe Simpson's infantry squad, implying the Wiggums emigrated to America by the early 1940s at the latest. In the episode "Mother Simpson", a teenaged Wiggum was a trainee security guard at Springfield University when Homer's mother Mona sabotaged the University's laboratory, which Mr. Burns was using for biological weapons. Antibiotics used to kill the weapons cured Wiggum's asthma, allowing him to join the police force. Many episodes have dealt with the back story of how Wiggum, despite his incompetences, occupies such a high role in the police force. As with those of most supporting characters on the show, they are jokes for one episode and contradict each other. Wiggum was temporarily promoted to Commissioner of Police for Springfield's state in the 2005 episode "Pranksta Rap". Chief Wiggum is the father of Ralph Wiggum, whom he loves and is patient of, but he sometimes does not understand his son's eccentricities.
