    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.

    Amy just killed as Bernadette

    I always thought that Mayim Bialik's talents were never truly used in her run on TBBT. She often showed how she could have been able to do much more with a character saddled with the "plain & boring" stereotype. Here we saw an example of peak Mayim.

    So, Howard dresses as Sheldon for Halloween. In retailation, Sheldon and Amy dress as Howard and Bernadette. Of all the imitations, Amy as Bernadette is a whole level over the rest. The way she nails the character is scary - helium-boosted voice included. It is also clear that Mayim is having the fun of her life (Simon Helberg as Sheldon too, but, IMHO, his was more a parody; Mayim just became Bernadette).

    What I didn't like in this episode is how deadly serious were the reactions by everyone. It was a callback to one of the earliest episodes, when Penny explains in strong words to Howard what a failure of a man he is. TBBT is not about this. Characters already get angry, make gaffes, end up humiliated (big time), only to recover and forge on. That should be enough. Here we are assisting to something that could lead to a real break up in friendships. I don't watch this show for this.

    Yet, this leads to the conversation between Sheldon and Bernadette, the first really intimate one between them. When Bernadette says that Sheldon can't know what means to be the smallest person in the room Sheldon, quite correctly, points out how he knows, because he went to high-school when he still was a kid. The whole scene is a nice one and the saving grace of the episode.

    (BTW, if Howard dresses as Sheldon, he and Bernadette have no right to complain if Sheldon and Amy do the same thing to them; just my 2 cents).

    Hilarious

    I thought the episode was great! The two couples imitated each other so perfectly! My only disappointment was that Penny should have dressed up as 'Penny' from 'Inspector Gadget'...

    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.

    Most Overrated Episode of Season 12

    I Seriously think an 8.3 is way too high. This episode is not that good. For starters Bernadette dares Howard to dress up as Sheldon for Halloween, fine; Sheldon does not instantly get the joke. Later Amy finds Sheldon is upset and decides you know what we'll get our revenge by doing the same to them.

    This episode shows that you shouldn't dish it if you can't take it. Giving my rating of 6/10

    *Decent at best*

    • 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.

      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.

      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.
