8 Simple Rules (originally 8 Simple Rules for Dating My Teenage Daughter for the first season) is an American sitcom, originally starring John Ritter and Katey Sagal as middle-class parents Paul and Cate Hennessy raising a family of three.

Kaley Cuoco, Amy Davidson and Martin Spanjers co-starred as their teenage kids; Bridget, Kerry and Rory Hennessy.
