Mad Men - Episode 9 Thread

What's in a Name - I'm a newcomer to this blog and a passionate Mad Men fan. Has anyone noticed Matthew Weiner's clever use of names? For example, the office problem drinker is named Freddie RUMson. I also really like the nostalgic names: Peggy, Betty, Sally, Roger, Don, Hildy, Jane, Ken, Kitty - these are names that almost no one gets anymore. Further, I wonder if Mr. Weiner thought up Crab Colson just to accommodate the delightful Crab Duck, Duck Crab introduction. Weiner very correclty is poking fun at typical Wasp nicknames of that era.
