For some reason, John's death hit me hard, and I still feel saddened when I think about how he died so suddenly, so young, and on his daughter's(?) birthday to boot. I remember him best from Three's Company.
I found the episode of 8 simple rules on YouTube where they address John dying (Goodbye). I cried the first time I watched it because it was apparent (to me, anyway) how upset the cast was; I half expected any one of them to burst into tears at any particular time.
