This may or may not be off-topic, but my best guess it that it's not. I
think I know this elderly actress from old movies or maybe old TV shows.
As best I can tell she didn't get a mention in the opening or closing
credits for last week's Mad Men. I've Googled and I've IMDB'd and I've
Wikipedia'd and I've given up on figuring it out by myself. But I'll bet
somebody around here can tell me the name of the actress who plays Roger
Sterling's mother. Maybe? Hm?
