Best episode so far: "Masters of Sex" Showtime Series 1, Episode 8 "Love and Marriage"

Was it me, or was this the best episode yet? Definitely the funniest.

Dr Masters has a thing that no mayonnaise should be left around his research area.That weird bit about chocolate brownies.
Lester, the movie geek, recruited to film 'interior' shots for the sex researchers, makes a throw away comment about Bogie and Agnes Moorehead in "Dark Passage" (Oh, pl-ease!). Then Jane does a Gloria Swanson with, "I'm ready for my close-up" (Mr DeMille). (Best line of the night)
Walter, the young handyman (yes, we are in Douglas Sirk 50's melodrama territory) teaching Libby the tango. That black dude beats Arthur Murray.

Then things get serious - Libby is pregnant again, selling pap smears to disinterested male doctors and evaluating marriage with Ethan (being forced to jump in the deep end too early) and Austin (jaded, part-time husband/father, sex addict).
"Married men live longer" (Ethan)
"It just seems longer" (Austin)
The confrontation in the bar with Margaret, Barton and Dale. Allison Janney is heartbreaking.
Barton and Dale talking about aversion therapy. Another strong scene.
The realisation that the glacial Dr Lillian DePaul is dying with cervical cancer. Wow, this explains a lot.
A great episode.
