Clarence "Clancy" Wiggum's biography

Chief Wiggum is of Irish descent. 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 Many episodes have dealt with the back story of how Wiggum, despite his incompetence, 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". He also appeared on Halloween novel depicting Stranger Things as chief Jim Hopper.

Despite his severe incompetence at his occupation, Wiggum on occasion has helped various other characters, such as helping Homer find his wife in "Marge on the Lam". He rescued Maggie Simpson when she ran away from home to look for Marge in "Homer Alone", by helping Lisa Simpson find Mr. Burns' assailant in "Who Shot Mr. Burns?" as well as helping backing her up in a school protest on one occasion in "The President Wore Pearls". In the episode "Pranksta Rap" he manages to find the presumed kidnapped Bart Simpson in Kirk Van Houten's apartment. He also arrived just in time during crucial moments such as the various times Sideshow Bob had attempted to kill Bart Simpson. Perhaps the best example of this is the episode "Mother Simpson", where it is implied that he leads the FBI astray in their search for Mona Simpson, allowing her to escape in gratitude for curing his asthma. Although Wiggum can often antagonize others as well, it is heavily implied that it is not out of malice but merely because he is doing his job or because he is ignorant of the situation.
