The Big Bang Theory Episode Recap: "The Maternal Capacitance" Season 2, Episode 15

After a dreadful visit from his mother, Leonard turns to Penny and tequila for comfort.

The episode couldn't have begun any better: Raj + karaoke = an awesome rendition of Red Hot Chili Peppers "Under the Bridge." The solo was quickly cut very short after Penny walked into the apartment because of the noise they were making. We then see Leonard on the phone with a mystery individual and Sheldon was analyzing who he could be talking to. It was obvious that whoever he was talking to, he was not very happy about it. Sheldon finally guesses that it must have something to do with a colonoscopy appointment. But was it? No, it was worse. Leonard tells the gang that his mom was coming to visit.

The following scene we see Leonard's mom, Beverly, played by the lovely and talented Christine Baranski, standing in front of the visibly broken elevator. Penny returns from doing laundry and sees her standing there staring at the yellow construction tape. Right away it is obvious that Leonard's mom is a little strange. After a very brief conversation, Penny quickly states, "You must be Leonard's mother," and walks with her up to his apartment. In this short period of time, Beverly manages to not only make Penny cry, but grills her on her childhood and "daddy issues."

The next scenes make it very clear that Leonard is truly suffering from her visit (and to be honest I don't know how he survived his childhood), but Sheldon seems to really be enjoying the company of Leonard's mom. Not only does Sheldon open up and tell the story of his mother hitting him with a Bible because he didn't eat his Brussels sprouts, but they both even go to the hospital together (Sheldon loves to get his head scanned) to analyze the brain together. This makes me wonder to myself: Is Sheldon in love with Beverly or is he just glad to have an older/sophisticated woman around him?

Meanwhile, Leonard goes over to Penny's apartment to get away from his mom. Penny had already begun drowning her sorrows in a glass a wine, and Leonard was right there to follow in her footsteps. Again, their childhoods are discussed and we learn that Leonard built a "hugging machine" when he was 10 (insert the "oooo's" and "awwww's here"). The next scene we find the two of them moving from wine to shots of tequila... which in my experience is never a good idea. Penny shows Leonard how to do a shot of tequila (salt, shot, lime). We then see a visibly intoxicated Leonard lick salt off of Penny's neck (and lick again), take the shot, then eat the lime... which Penny was hiding in her mouth. Finally, in a very surprising twist, we see the two of them kiss! Wahoo!

Eventually this make-out session goes from the couch to the bedroom. Was this it? The day we would actually see Penny and Leonard "get together." Again, we were left disappointed. Leonard opens up his mouth a little too much and wonders how his mother would analyze this bedroom scenario. He finally tells her that he's in bed with his mom, and Penny's in bed with her dad. "You're trying to have sex with your father and I'm okay with that," Leonard states. This disgusts Penny (and rightfully so) and she quickly kicks him out of her apartment. And if it wasn't bad enough for poor Leonard, he returns to his apartment to find Sheldon and his mom singing karaoke. I don't know about you guys, but I was waiting to find Sheldon and Beverly in a more intimate situation... but I should've known better.

Just like the very beginning of the episode, it ends with Penny crying and telling her childhood feelings to Leonard's mom... only this time she was walking her out of the building. Bye-bye, Beverly!

So, what were your thoughts on this weeks episode and Leonard's mom? For some reason she was not what I expected. And even though Penny and Leonard "made up," something still tells me that this is not over between the two of them.  Also, if you're like me and want to look like Sheldon, then you have to check out this site called Sheldon's Shirts!

And as always, below are some of the best quotes from this week's episode. I know I didn't get them all, but feel free to add your favorite!

"You found it. It's the sound of a cat being run over by a lawn mower." ~ Penny's response to the guys finding their sound

"If you want to have intercourse with that girl, find out what cologne your father wore." ~ Beverly's advice to Leonard after first meeting Penny

"I very much would like to read about your sex life." ~ Sheldon

"You brought your husband to work... you know the rules. ~ Leonard talking to Howard and Raj
