The Big Bang Theory Episode Recap: "The Classified Materials Turbulence" Season 2, Episode 22

While on a date with Stuart, Penny makes an unexpected discovery regarding Leonard.  Meanwhile, Wolowitz ask his friends' help on his NASA project when he uncovers a design flaw.

This week's episode began with the guys hanging out at the comic book store. "Smell that? That's the smell of new comics," Sheldon said as Stuart opened a new box of the latest reading materials. Howard even offered to pay for the comic books because of the money he is making with his new job working on a classified project for NASA... the only problem is he is working on a toilet for the space station. But not just any toilet, it was the Wolowitz Zero-Gravity Waste Disposal System. Stuart came over and handed Sheldon the latest "mind-blowing" Hellboy comic book, but Sheldon was immediately offended by that statement. "Spoiler Alert next time!" Stuart then turned to Leonard and told him that he is going on a second date with Penny. I had to agree with Leonard's reaction to this statement because I was surprised that there would even be a second date. Stuart then asked for Leonard's phone number in order to get some advice from him.

The next scene showed Leonard and Sheldon having lunch in the cafeteria, when Leonard got a phone call from Stuart. Leonard seemed to be avoiding the awkward conversation at all costs and decided to ignore him and let it ring. Sheldon told him that he should answer his call because perhaps the comic-book store could be on fire and that maybe he needs assistance. Leonard dismissed that theory and then he saw that his phone had a voicemail. "Aren't you going to check you message!?" Sheldon exclaimed as he continued to let Leonard know that by him not doing so was breaking a contract. Then Leonard said something to him that I have been thinking for the past two years: "It must be hell in your head." All of a sudden, Howard came to the table and yelled, "Code Red!" He let them know that he made a miscalculation on the toilet and it will fail after 10 flushes. Not only does he not want to notify NASA of this dilemma, but he also needed help from the other guys.

Back at the apartment, Howard brought an exact duplicate of the human waste distribution system and the parts that were needed to fix it. Before they could begin work on the toilet, there was a knock on the door. It was none other than Stuart. Leonard apologized and let him know that he wasn't answering his phone or checking his email because "everything is broken." Yeah... riiight. Stuart must really want some advice from Leonard! Finally, Leonard gave Stuart last minute advice.  He told him to go slow (glacier slow), have absolutely zero eye contact, and have fear (as is you touch her she will break). Stuart seemed to be totally content with this advice and went off to pick up Penny.

After pulling an all-nighter working on the Zero-Gravity Waste Disposal, Leonard decided to go over to Penny's apartment to see how the date went.  Was anyone (like me) expecting Stuart to answer the door? Anyway, Penny answered the door and immediately wanted nothing to do with the conversation about what happened on their date and closed the door on poor Leonard. As he went back to his apartment, Leonard decided to go to the comic book store to talk to Stuart, because his conscience was getting the best of him. The other guys weren't aloud to go because the prototype was ready and it was time to try it out using Howard's mom's meatloaf to act as human waste. "3... 2... 1... poof!" Literally the sh*t hit the fan and the meatloaf was stuck to the ceiling. Sheldon put it best when he looked up and said just one word — "fascinating."

Meanwhile at the bookstore, Leonard met Stuart and found out the date "went to hell." It turned out that everything seemed to be going well, but it wasn't Leonard's advice that made the date turn out this way. Soon after a few bottles of wine (and during a make-out session) Penny said, "Oh Leonard." Stuart seemed surprisingly okay with the fact that Penny was not into him and obviously still hung up on Leonard.  The funniest line of the night was when Stuart then said, "Well, it beats... you know I'm a dude, right?"  Immediately you could see that Leonard was ecstatic about this and he left the comic book store he began to jump for joy.

What were your thoughts? The last few seconds when the astronauts gave the "FYI" to Houston was great, but I still can't get enough of Sheldon's laugh (that we seem to be getting more and more of every episode). Next weeks premise on the second season finale: Penny is conflicted when Leonard and his friends decide to spend the summer working — at the North Pole. I can definetly see Penny getting emotional when the guys leave. What would she do all summer? Below are also some of the great one-liners of this week's episode...what was your favorite? 

"Have you been selling your sperm again?" ~ Raj
"Thanks for close captioning my pain, Raj." ~ Leonard
"You mean... so it doesn't hit the fan." ~Raj
"Have you seen the size of the Russians they got up there?" ~Howard
"Not enough bread crumbs." ~Raj

Premise: Two nerdy physicists share an apartment and an unlikely friendship with their beautiful neighbor with whom one of them is infatuated. Like the universe after the big bang, the show's popularity expanded, thanks to breakout star Jim Parsons, along with the chemistry among the friends and the developing romance between Leonard and Penny. The addition of Melissa Rauch and Mayim Bialik in later seasons also enhanced the stories and relationships of the leads.
