Episode cast overview:
Debbie Wolowitz (voice)


After a group dinner at Leonard and Sheldon's apartment, Leonard and Amy are the unlikely pair left alone at the apartment as everyone else goes off for the evening. Despite it being a somewhat uncomfortable evening for Leonard, he agrees to accompany Amy to an upcoming wedding, she who refuses to take Sheldon based on a past incident. At the reception, Amy, who "whored" herself up to meet her perception of social convention, is the one of the two who tries to enjoy their time together in this social setting. Leonard ultimately appreciates Amy's attempts. But both Amy and Sheldon misinterpret Leonard's appreciation. Meanwhile, Howard tells a disbelieving Bernadette that he expects them to live with his mother in her house after they're married. After an argument, Bernadette at least agrees to go through a trial weekend at the Wolowitz house. And Sheldon is off in his own literally little world as he plays with his new HO model train set.

Crazy Credits


I have long believed that we as human beings are genetically inclined to elevate and worship those of us we deem to be very beautiful or very talented. We do this because we are somehow comforted by our adoration. It makes us feel good. As children we sleep beneath the images of movie, TV, music and sports stars and dream about the mystery and grandeur of their lives. As adults, the posters come off the wall, only to be replaced by a steady, noxious stream of tabloid culture. But perhaps most enjoyable of all is watching the fall from grace. Nothing beats a good ol' public crucifixion. Especially when it's self-inflicted. My theory for why this is considered entertainment is, again, a genetic one. DNA, even if it's mediocre, wants to ensure its own survival. The existence of superior DNA is viewed as a threat. When beautiful and talented people screw up, we can't help but feel that this somehow improves the chances for our mediocre descendants to eat meat. In other words, evolution my ass. See more »

"The Pulled Groin Extrapolation" was another pretty funny ep of "The Big Bang Theory"
17 November 2011 | by (Baton Rouge, La.) – See all my reviews

In a nutshell about this season's ep of "The Big Bang Theory": Sheldon wants to stop at a train store and since Penny has to go to work, it's Raj driving him there as well as Howard and Bernadette to the movies. During the ride, Howard blurts out she's going to move in with his mother after the wedding which doesn't sit too well with Bern. But she eventually agrees to try it for a while. Meanwhile, Amy has stayed back at the apartment while Leonard tries to work on the computer. After some awkward talk, it seems Amy wants Leonard to be her date to a wedding since Sheldon doesn't behave himself well at those things, at least according to Amy. I'll stop there and say that while this ep wasn't as funny as the first two this season, it still had some moments such as Bernadette's impersonation of her future mother-in-law and Amy's characterization during the whole thing. So on that note, I rather still enjoyed "The Pulled Groin Extrapolation" ep of "The Big Bang Theory".
