Hence the analogy with the Munich Agreement of 1938 from a couple of episodes ago.

Whatever happened to Joyce?  I always thought she added a sense of vitality to Peggy's storyline, as a youthful counterculture type, but I guess the actress playing her is too busy being Shosanna in an alternate TV universe.

Benson seems to have numerous functions.  He fetches toilet paper, sends out unsolicited platters to funerals, always seems to have a spare coffee ready to go, acts as a wingman happy to pay for Pete's kicks at a bordello, and reassures clients that he has 'met them before', all while asking for nothing in return.

Like Don said at the end of Season 3 just before they broke away and formed SCDP, he is interested in building something, producing great work, and he realised that with the McGann Erikson takeover they were being bought and sold by Accountants wanting to 'turn a dollar into a dollar ten', hence forming of their own…

"Did you enjoy ze Führer's birthday?"

Probably better to own a Chev Vega than own a Ford Pinto, with it's notorious rear-mounted fuel tank.

Don said last season he wanted Chevy. Be careful what you wish for, I guess.

Chaough is kind of like a younger version of Duck, charming, smarmy and scheming, but without the alcoholism or PTSD.

And Sally Draper joins the Weather Underground.

Betty, being the immature, emotional cripple she is, would probably relate to what Don is say if she was to be completely honest.

Up until this episode, Bobby Draper has been interchangeable, much like a piece of furniture in the SCDP office.

I think is was a verbal slash against Megan, much like Betty's 'Child Bride' remark last season.  Betty is naive enough to believe Don and Megan are happy, considering her malicious reference to Anna Draper last season.

Google might disagree with you.

You could say the same thing about Tony Soprano.

Maybe the producers were messing with the Community fans who only watch Mad Men so they can see Allison Brie.

Also, a song from The Velvet Underground would be appropriate considering this show is set in NYC in the late 1960s.

True , but least there is no cumbersome pillar and it has a view.

SCDP got third prize as far as the Beans guy is concerned.

Maybe it's Don, as an ad man, being one step ahead and foreseeing the way public opinion is heading regarding the war.  Television news anchor Walter Kronkite had recently spoken out negatively of the war, so what Don is saying reflects what is going on in the media.

Did you notice in the very next scene when Don walks into his apartment, the radio is on and Robert Kennedy's name is mentioned, so yeah, there's a bit of foreshadowing there.
