    This is a sitcom, not a civics class

    Had to try to balance some of the negative reviews. To the people who called it offensive: get over yourselves. It's a situation comedy, meant to make you laugh. I thought Howard, Amy and Sheldon all did a hilarious job imitating their friends. To the people who called that bullying: people rag on their friends, it's normal behaviour. Not to mention it's the plot line for probably 80% of sitcoms, and certainly at least half of The Big Bang Theory. You belittle actual bullying (which of course is a real problem and should not be tolerated) by freaking out about this. Easy to sit at home typing and complaining about tv shows, I guess.

    Finally some laughter

    The promo looked so bad but this episode was funny. Finally made me laugh in a long time watching BBT and not just pity laughs because-I'm-investing-my-time-so-I-may-as-well-laugh laughs. Keep it up guys!

    Best episode in quite a while!

    I can't remember when I laughed so much at a TBBT episode. The imitations were hilarious, and love it when Bernadette gets called out for being so mean. Bernadette being mean is never funny. I hope the laughs continue like this for the rest of the series.

    Best episode in last couple seasons

    Well, this was finally a positive surprise - much better than average ep. of last couple seasons. Imitations were hilarious, and I liked especially talk between Bernadette and Sheldon near to end. I felt while watching this like felt when watched early seasons. Well deserved 10.

    So funny.

    This is one of the funniest episodes of all, when they dressed up as each other they pulled it of perfectly, it was truly hilarious.

    Howard is so funny and very good at impressions.

    I've said it before and I'll say it again, every character in the show is so funny, Sheldon, Leonard, Howard, Raj, Penny, Amy, Bernadette, Stuart, Kripke, Zach, all of Raj's girlfriends, and all of the cameo appearances have been so good and so funny it's made every episode so so great.

    And omg how beautiful is Kaley Cuoco? She is so radiant and such a good actress, to think she nearly didn't get the part of Penny.

    Storyline

    Did you know

    • Trivia
      Leonard and Penny's first kiss happened in The Middle Earth Paradigm (2007), indeed during their first Halloween together. Most of what she says occurred in that episode, except for her vomiting in a pumpkin, which must have happened off screen.
    • Goofs
      Amy tells Sheldon that he doesn't always correct people. She give the example of how refrained from telling Penny that she ended a sentence with a preposition. This chestnut (which crops up in other episodes) is wrong because there is nothing wrong with ending with a preposition. The prohibition against it is an artificial, 17th century attempt to align English grammar with Latin's. That is the kind of pedantic fact that Sheldon should know.

      Howard Wolowitz: [Howard joins Sheldon walking down the corridor] Hello.

      Sheldon Cooper: Hello.

      Howard Wolowitz: I see you are dressed as Doc Brown from Back to the Future. May I assume that Amy is going as his wife, Clara Clayton, from Back to the Future Part III?

      Sheldon Cooper: She is.

      Sheldon Cooper: [Sheldon stares at Howard] Did you do something different to your hair?

      Howard Wolowitz: Yes.

      Sheldon Cooper: Looking good.

      [and walked off without realising Howard is dressing up as him]

      MY PRAYER

      God, (I call you that even though I suspect thou art well beyond names and words and might actually be some sort of ineffable quantum situation), I humbly beseech thee to make thy presence known on November 6th. Demonstrate your omnipotence through us as we make ink marks on little circles in curtained booths. Of course if you, in your divine wisdom, believe a fascist, hate-filled, fear-mongering, demagogic, truth-shattering, autocratic golf cheater is what we need right now, then, you know, thy will be done. But if thou art inclined to more freedom, more love, more compassion, and just more of the good stuff thou hath been promoting in our hearts or our parietal lobes - either one, doesn't really matter - I submissively ask that thy encourage voter turnout in that general direction. Also God, please help Bob Mueller. Guide him and make him strong, brave, wise and true. And yes, I know there must be thousands of guys named Bob Mueller, so why not help them all, just to be on the safe side. Amen. Oh, almost forgot, remind those who collaborate with the darkness that thou art the light, and the light is not above whipping out a little Old Testament wrath. Amen again.
