A List Of Things Thrown Five Minutes Ago

GUESS I'LL ALWAYS CA-A-A-A-A-RE: Now this felt like Mad Men. Last week was worth the price of admission for Sal's, er, cooling experience with the air conditioner, but the goings-on at Sterling Cooper this week felt much more organic than Don's sojourn down to Baltimore to boink stewardesses and talk about how there will always be rain. And now we know what the rest of the season is going to be about. We can talk about substance in the comments, but just a few thoughts out here:

• How insanely dated did that Ann-Margret clip feel? And how great was Peggy's awkward effort to play girly-girl in her mirror? I'm glad to confirm that Elisabeth Moss is actually 27, because she looked positively antediluvian compared to the little college guy.
• I didn't catch the relevance of Margaret Sterling's wedding date until Alan mentioned it. That should be interesting.
• I find January Jones somewhat attractive in real life, but man, she was just born to live in the early 60s. Unrelatedly, the look she shot Don when Don resolved her family situation with about as much authority as he used on Bobbie Barrett last season -- it does serve to remind that while Betty Draper may be cold and aloof, the actress portraying her is not. That being said, I'm not sure why Don thinks this is the right solution to the family's problem.
• I didn't understand what Don was saying to Peggy when he told her to "leave some tools in your toolbox" -- was it just "don't try to be everything to everyone all at once" or is there something else I'm missing?
