John Ritter died on September 11, 2003, four episodes into the second season of "8 Simple Rules for Dating My Teenage Daughter." He was 54.
The sitcom was ABC's family-comedy anchor, and its star had just finished filming what became his final scenes days earlier.
Two decades on, the story of what happened to that show — and to the people who loved him — remains one of the most quietly devastating chapters in TV history.
Ritter collapsed on set during a rehearsal for an episode titled "Goodbye." It was a Friday.
He was rushed across the street to Providence Saint Joseph Medical Center in Burbank, where he was pronounced dead that evening.
The cause was an aortic dissection, a tear in the body's main artery, a condition that can strike without warning even in people who appear healthy.
The irony was almost unbearable for everyone involved.
Ritter had spent his career as television's most reliable comedic engine — Jack Tripper on "Three's Company," a role that won him an Emmy and made him a household name for a generation.
On "8 Simple Rules," he was doing the same thing again, playing the exasperated dad to Kaley Cuoco and Amy Davidson, trading jokes with Katey Sagal.
ABC faced a decision that no network ever wants to make.
The cast and crew were devastated, but they chose to continue — and they did it in a way that still feels radical.
Instead of recasting or writing him off in a throwaway line, the show addressed his death head-on.
Season two's third episode, "Goodbye," aired in November 2003 and drew more than 18 million viewers, becoming one of the most-watched broadcasts of that fall.
The episode opened with Ritter's character, Paul Hennessy, simply not coming home.
No body, no funeral footage, just a family learning to sit in a room where the center of gravity had vanished.
James Garner and Suzanne Pleshette guest-starred as Paul's parents.
The cast filmed it in a single week, and by most accounts, they were not acting much at all.
Cuoco has said in interviews that the experience shaped how she understood loss at 17 years old — and how she understood what a workplace could mean to a person.
What's striking now, in an era of constant reboot and revival news, is how the show handled the aftermath. "8 Simple Rules" ran two more seasons, retooled around Sagal's character and a new set of storylines.
It never recovered its original energy, and it ended in 2005.
No one tried to CGI Ritter back into a final scene.
No one recut old footage to give him a farewell monologue.
The show grieved in real time, on network television, in front of millions.
The other thing worth remembering is how much Ritter worked.
He was in "Sling Blade," "Problem Child," and a hundred other things, always with the same loose-limbed, rubber-faced energy that made him impossible to dislike.
His son Jason Ritter has since built a career of his own, and the resemblance in interviews — the timing, the warmth — is uncanny in a way that's both lovely and hard to watch.
Streaming has given Ritter a second life. "Three's Company" episodes cycle endlessly on free ad-supported platforms. "8 Simple Rules" pops up on Hulu and across retro TV blocks.
Every few years, a clip of Jack Tripper falling over a couch goes viral on social media, and a new crop of viewers discovers why their parents laughed so hard.
The tributes will keep coming every September, and they should.
But the real legacy isn't the sadness of that day in Burbank.
It's a body of work that still makes people laugh, and a TV family that chose honesty over easy fixes when it mattered most.
Some stars get remembered for how they died.
Final Thoughts
Ritter deserves to be remembered for how reliably, generously, and joyfully he worked right up until the end.
