I am watching the show over again and at least in the earlier seasons, a lot of the actors are dead.

Its kind of creeping me out.

What about you?

No. I love seeing all the old tv shows and I love old movies. Most of them are dead.

No, about the only people I'm uncomfortable watching are actors who I know were troubled while they were making the show, such as Patty Duke.

Cast members and recurring, still with us from the black and white era, roughly in order of their intros:

Stanley Livingston (Chip) b. 1950
Cynthia Pepper (Jean) b. 1940
Ricky Allen (Sudsy) b. 19-??
Debbie Megowan (Dorine) b. 1953
Barry Livingston (Ernie) b. 1953
