Stars always die in three's. It's a very odd thing, but it does seem to happen a lot.
This was an absolute shock. He was only 54, and he died of a heart ailment. John Ritter was a big star when I was growing up. I loved his show 3's Company. He was the son of country star Tex Ritter. I loved his physical style of comedy. You don't see that much anymore.
I wonder what they are going to do about his current tv show? Cancell it, or write him out. It was smash hit for ABC.
A very sad loss. He will be missed.
