Diane Sawyer's ABC tribute special, John Ritter: Life of Laughter, attracted over 14 million viewers on Tuesday night. Sad pals and co-stars tearfully reminisced about the 54-year-old Three's Company alum, who suffered a fatal aortic dissection last week on the set of his latest sitcom, 8 Simple Rules for Dating My Teenage Daughter. As previously reported, ABC plans to continue Rules by writing the death of Ritter's character into the show's storyline.
