Chief 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, and is the father of Ralph Wiggum and the husband of Sarah Wiggum.

The theory suggests that, at some point, Eddie had an affair with Sarah Wiggum. The affair resulted in the birth of Ralph, making Eddie his biological father. It wouldn't be unlikely for Eddie and Sarah to have crossed paths given both of their connections to the police department, so the idea is plausible.
