Dana Plato, who played Kimberly on the 1980s sitcom "Diff'rent Strokes", is most certainly dead. Surprisingly, Willis and Arnold still live on. I'm not quite sure how Mr. Drummond is doing. Either way, Plato was ultra hot, and committed suicide by overdosing on prescription drugs in 1999, at the age of 34. The picture above is from an old-school Noxema ad.
