8 Simple Rules

8 Simple Rules (originally 8 Simple Rules... for Dating My Teenage Daughter) is an American television sitcom originally starring John Ritter and Katey Sagal as middle-class parents Paul and Cate Hennessy, raising their three children. Kaley Cuoco, Amy Davidson, and Martin Spanjers co-starred as their teenage kids: Bridget, Kerry, and Rory Hennessy. The series ran on ABC from September 17, 2002, to April 15, 2005. The first season focused on Paul being left in charge of the children after Cate takes a full-time job as a nurse, with comedic emphasis on his often strict rules concerning his daughters and dating. The series' name and premise were derived from the book 8 Simple Rules for Dating My Teenage Daughter by W. Bruce Cameron.

While 8 Simple Rules was renewed for a second season and production had begun, Ritter's sudden death on September 11, 2003, left the series in an uncertain position. After a hiatus, the series returned and killed off his character. James Garner and David Spade later joined the main cast as Cate's father Jim Egan and her nephew C.J. Barnes. After three seasons, ABC cancelled 8 Simple Rules in May 2005 because of low ratings.
