Cuoco spoke about Ritter, who died at the age of 54 in 2003, at a September 12 benefit for the John Ritter Foundation for Aortic Health inside Hollywood’s Sunset Room to TV Insider. 

During the event, Cuoco portrayed Janet Wood, originally played by Joyce DeWitt, in an episode reading from the 8th and final season of Three’s Company, which aired in 1983. As fans of Ritter are aware, the comedian famously played chef Jack Tripper in the beloved sitcom.

During the TV Insider interview, Cuoco shared that Ritter, who played the Hennessy patriarch, Paul Hennessy, on 8 Simple Rules, taught her to do whatever it takes to get the audience to laugh when doing comedic roles.

“The most important thing I learned from John was to do anything for the laugh. I live by that today. [Working with John] changed the course of my life and my career. It feels like yesterday,” said the Big Bang Theory star, who played one of Paul’s daughters, Bridget, in 8 Simple Rules.
