When Sally is watching TV at her sleepover, David McCallum is on the TV. Audiences today know him as Ducky from NCIS, but this was a show he was on in the 60s, The Man from UNCLE. I liked both NCIS and Mad Men so I was quite chuffed to see it.
Otherwise great episode. I like the game theory ("chess match") between Draper and Shaw. Draper shows his ingenuity.
Sterling's digs at the Japanese were well written. Interesting to see a view on the differences between WWII generation and the ones too young for it. 1965 was only 20 years out from the end of WWII. I'm sure it wasn't easy for some people to go from anti-Japanese propaganda during the war to having them be new business partners. Betty is unchanged and still unhappy in her new life. Everything is all about her.
