Mr. Turner

Mr. Turner, most commonly known as Dad, and is called simply "Turner" in "Dimmsdale Tales" (voiced by Daran Norris) is Timmy's father. He is usually depicted as one of the most idiotic characters on the show, rivaled only by Cosmo (and even then Cosmo is considered smarter). As a running gag throughout the series, his first name has never been revealed, with people almost always referring to him as Timmy's Dad (even by people who are not related to him); something such as a truck noise usually blocks the revealing of his actual name.
