So, let me get out of the way what is sure to be an unpopular position: I didn't find that estrogen cream and boob testing schtick to be all that funny. I mean, it was sort of amusing -- and better than it would have been on other shows because it had an extra kick of exaggeration and was well-acted. But overall, Howard being a stereotypical woman, whatevs. And then his getting into some kind of double-entrendre with Raj-- both oblivious to it -- that was sort of funny but we've seen it before and it went on too long. And while they managed to tie it in with the Penny/Sheldon story at the end with that joke- meh, that was kind of gross. I like how Bernadette just walked away - because really, what else can you do in that situation with those two dufuses.
Not to say there weren't good moments in this episode. The bit with Stuart rooking Sheldon was really good exploitation of Sheldon's achilles' heel: his naivete about the real world. Poor Aquaman never gets any respect. The sailor hat, also a nod at Sheldon's childlike enthusiasm for things, was also good. And Amy not taking Sheldon's guff about "the friend of the girlfriend of my enemy" warning. I love when she tells him off. It's so "real couple."
When Sheldon went back to knock again- I knew it was coming, but it was still funny. Speaking of doors, I also liked the high pizza man and Penny telling him off than Sheldon noticing his "earthy" smell.
I kind of liked Leonard and Penny having a secret from Sheldon. It seems like a lot of the time in the past, Leonard has been trying to keep something from Penny - and hilarity ensued. I like this variation. I'm sure we've seen it before. Anyone think of it? And I like their solid-ness as a couple.
Until next week, BBT fans. And please do share your thoughts on the season's first episodes below!
