On ET tonight they will have a spechail thin I don't know what's it about but they DO mention John Ritter...here is the rest of the page if you'd like to see.

"He has a very simple tombstone," she reveals about the "Three's Company" star who died in 2003. "It has his name and a very nice quote from the BEATLES. I believe it's off the White Album and it says, 'The love you take is equal to the love you make.' I had heard John Ritter was a big fan of the Beatles and I think it (the tombstone) was more his wife's doing because he died so suddenly. It's a very appropriate epitaph for him."
