    They Feel Flushed

    Two general directions. One involves a space toilet designed by Howard that he realizes won't work. But they are already on their way to the space station. Panic. Meanwhile, Stuart is about to have his second date with Penny so he asks Leonard for advice. This one didn't have the spark that most of them have.

    The Classified Materials Turbulence: Secrets, Humor, and Geek Antics

    This episode features the gang dealing with classified materials and the resulting chaos. Humor arises from their scientific approach clashing with real-world rules, producing awkward and comedic situations.

    Pros: clever humor, strong group dynamics, entertaining character interactions.

    Cons: straightforward plot, predictable situations.

    Verdict: A fun and light episode that highlights the gang's quirks while delivering consistent laughs.

    My rating: 8/10.

    The Classified Materials Turbulence

    At only around 17 mins this episode felt even zippier than normal, but despite perhaps a thin story, does offer some subtle advancement in the whole Penny/Leonard arc.

    A nice episode, but a bit too short for its own good.

    • Trivia
      The scene where the guys try to solve Howard's defective waste disposal system with spare parts that are also available to the crew on the International Space Station spoofs a similar scene in Apollo 13 (1995), in which NASA techs on Earth use objects also available to the Apollo 13 crew in an attempt to fix their failing carbon dioxide filtering system. This episode also has a scene where an astronaut calls to Houston to announce "a little situation" (analogous to the famous "Houston, we have a problem" line from Apollo 13).
    • Goofs
      In the opening scene, Stuart is removing new comics from their shipping box, to the left of the cash register, and putting the stack of books on the counter to the right of the register. After the next cut-away, the box has moved to the right side, into the space Stuart was using to check in the books.
    • Quotes

      Stuart: Here, Sheldon, I pulled the new Hellboy for you. It's mind-blowing.

      Sheldon Cooper: Excuse me! Spoiler alert!

      Stuart: But I didn't spoil anything.

      Sheldon Cooper: You told me it's mind-blowing, so my mind is going into it pre-blown, and once a mind is *pre*-blown, it cannot be *re*-blown.

      Stuart: I'm sorry.

      Sheldon Cooper: Said the Grinch to Christmas.

    • Crazy credits
      CHUCK LORRE PRODUCTIONS, #250 For months I've woken up to a mysterious, intermittent banging sound coming from somewhere in my home. I can't tell you how many mornings I groggily walked around in my pajamas searching for its cause. Frustrated by my inability to locate the source of the banging, I falsely accused my ancient refrigerator and began seeking a replacement. But then I caught a break. Rising early one morning for reasons urinary, I stumbled across the real source of the strange noise - - a small, yellow-breasted bird living the a tree next to the kitchen window. Periodically, he would fly to the window, furiously peck at it with his beak, then quickly retreat to a nearby branch. At first I assumed that the morning light caused him to see his reflection and, being of limited intelligence, or filled with self-loathing, attack it. But once again, my initial instinct proved to be wrong. After a long conversation with the bird, I learned that he was banging on the window because he had it in for my refrigerator. I have since apologized to the fridge, but it has been, not surprisingly, cool towards me. Sorry, that really wasn't worth the journey.
