I don't think I ever saw "The Addams Family." Not in full, anyway. But in the comic strip "Non Sequitur," there was a family called the Gravesytes; the dad looked like a stockbroker, but he carried his head around on a plate, the mom was some kind of weightless wraith (a former fashion model, according to the kids), the teenage son always wore a featureless mask and the daughter was a cheerful little ghoul.
A couple of nights ago, I dreamed that I had gotten a hold of Richard's high school yearbook. And last night, I dreamed that I was looking at a photo of him as a kid. In the photo, he was standing in front of the house, wearing a parka, jeans and (of course) Adidas. He was about 13 or 14, and the photo seemed to have been taken in winter.
