    The Sex Drives Off

    We start with an hilarious reconstruction of a Civil War battle using condiment bottles and other stuff at the Cheesecake Factory. We meet Leslie Winkle (Sara Gilbert) for the first time and she comes on to Sheldon. This sets up the episode when the two of them get together. I didn't realize that there was already some sexual tension between Leonard and Penny. Anyway, we have the big time scientist versus his basic feelings. The humor here comes from Sheldon getting in the middle of things.

    The Big Bang Theory - The Hamburger Postulate: Science Meets Everyday Life

    This episode continues the humorous interactions between the main characters and their new neighbor Penny. It shows how their scientific mindset clashes with everyday situations, creating comedic moments and highlighting each character's personality.

    Pros: engaging dialogues, character-driven humor, light and enjoyable atmosphere.

    Cons: plot remains simple and predictable, typical for early sitcom episodes.

    Verdict: A fun and light episode that reinforces character dynamics and keeps viewers engaged.

    My rating: 8/10.

    The Hamburger Postulate

    In these early days of 'TBBT' it really was all about Sheldon, Leonard and Penny, with Raj and Howard barely getting a look in.

    I don't actually mind that, it's quite fun to see the show in this form.

    There's lots of lovely moments here, with some sharp lines and interplay.

    Good fun overall.

    • Quotes

      Sheldon Cooper: [furious that Leslie wrote on his board] I don't come in to your house and touch your board!

      Leslie Winkle: There are no incorrect equations on my board.

      Sheldon Cooper: Oh, that is so... so...

      Leslie Winkle: I'm sorry, I gotta run. If you come up with an adjective, text me.

      Sheldon Cooper: [after Leslie leaves and a brief pause] Inconsiderate. THAT is the adjective! Inconsiderate.

    • Crazy credits
      CHUCK LORRE PRODUCTIONS, #189 Last winter the magazine Entertainment Weekly did a story about me in which I was called "the angriest man in television." When the article came out I shrugged and said things like, "Oh, it's just a trashy tabloid, it doesn't mean anything." But you know what? That's a lot of crap. It's taken me ten months to get in touch with my feelings about that article (pretty quick for a guy), and guess what? I'm angry! How dare anyone suggest I have no right to feel what I feel? If you're even barely engaged in this world, anger manifests itself constantly (assuming you're not medicated, which I am not, dammit to hell!). And let's be totally honest here, anger does a lot of good. It clenches my stomach muscles into a tight knot so I can look good with my shirt tucked in. It adds hours and hours of productivity by keeping me awake until five o'clock in the morning. It's a constant reminder that I should never own a gun. It makes golf an opportunity to practice my javelin toss. It fills me with joy every time Lewis Black is on The Daily Show. It adds sizzle to caffeine. It whispers to me that I'm fine, that I don't need to slow down, and that my cardiologist is an idiot. It keeps people at a healthy distance during flu season (and the rest of the year as well). And finally, it encourages me to use my vanity card to foolishly burn bridges with TV critics. Hey EW! Do not screw with me. I've got two vanity cards now, and I'm not afraid to use 'em Okay, the sun's coming up, I'm gonna try and get some sleep.
