  • Jesse Schedeen for IGN- "The Gorilla Dissolution" divided its time pretty evenly among three pairings - Howard and Bernadette, Leonard and Penny, and Sheldon and Raj. Only poor Amy was mostly left out of the fun,...One would think Sheldon would be completely ill-equipped to guide Raj through his latest heartbreak. But maybe Professor Proton's parting wisdom from last week is still rubbing off on Sheldon. He offered some surprisingly sound advice At this point, Sheldon is in danger of becoming a well-adjusted person. It was almost a relief to see him shoo Raj out the door so he could stick to his rigid bedtime. Another thing Season 7 has been better about is using Sheldon a little more sparingly...And Leonard directly addressed the notion that he's her safety net in life. Calling Leonard "the bran muffin" of Penny's life is pretty apt. So it was yet another awkward, fumbling marriage proposal. But the writing and the acting sold the ordeal enough that I was willing to accept that this is finally the right time for Leonard and Penny to stop screwing around and move their relationship forward...At least the payoff was worth it."
  • Dhruv Rao of The DR Club gave the episode an A grade, stating that, "the anticlimactic engagement followed by the romantic proposal was another plus point." [1]

Costume NotesEdit

Trivia Edit

  • Penny and Leonard are finally engaged after numerous rejected proposals:
  • Third appearance of Wil Wheaton in the seventh season; the most appearances Wheaton has made in any season.
  • Leonard is drinking Negra Modelo and Penny and Wil Wheaton are drinking Sierra Nevada Pale Ale in the bar.
  • Howard and Bernadette are only seen in Mrs. Wolowitz's house in this episode.
  • Penny's role as Town demolishes veteran's house while he has surgery Anne Frank in a theater above a bowling alley was mentioned in "The Terminator Decoupling" (S2E17) and "The Psychic Vortex" (S3E12), and she won the role for the hemorrhoid TV commercial in "The Skank Reflex Analysis" (S5E1).
  • Sheldon referred to Penny as a gorilla when he tried to teach her physics in "The Gorilla Experiment" (S3E10).
  • Amy only appears in one scene in this episode.
  • Bernadette previously called Howard a 'putz' in "The Engagement Reaction" (S4E23).
  • Raj and Emily consummate getting past their jealousy issues in their relationship.
  • Like in "The Proton Resurgence" (S6E22), Howard and Bernadette again talk about one day starting a family and being prepared to take care of their own baby.
  • It gets pretty obvious Sheldon is happy and secure with his relationship with Amy since he points out that he's not afraid of Amy being with someone else because she cannot have physical contact with another person, but him, despite that they haven't had sex yet. In "The Cooper/Kripke Inversion" and "The Love Spell Potential" (S6E23), he has admitted openly that he might someday have sex with Amy, so his happiness may be unseen partial excitement on looking forward to that day. Another reason Sheldon is happy is that they are in a steady relationship, which ironically began when Sheldon became jealous of Amy and Stuart on a date in "The Flaming Spittoon Acquisition".
  • Behind the director is a gorilla mask with a blonde wig which would be Penny's final transformation into her bi-sexual killer go-go dancing gorilla character.
  • The scene where Howard and Raj are struggling to bring an exercise machine upstairs only for it to slide onto someone off-screen is similar to the scene in "The Nerdvana Annihilation", where the nerds struggle to bring a prop time machine upstairs only for it to slide onto Howard and Raj offscreen or in "The Big Bran Hypothesis" where Sheldon and Leonard are bringing Penny's new entertainment center up the stairs.
  • Second episode where someone sees their love interest with another man and Sheldon helps them with their problem. First was "The Fuzzy Boots Corollary".
  • Second episode where Howard impersonates Bernadette. First was "The Holographic Excitation".
  • Leonard and Penny get engaged exactly two years, by episode number, after Leonard proposed to her during sex in "The Launch Acceleration".
  • From the pilot: "Leonard: Our babies will be smart and beautiful" "Sheldon: Not to mention imaginary." With the news of their engagement, Leonard's first crush reaction about Penny will become a reality. What Leonard doesn't realize is the the odds are the same for their children to be dumb and plain (His looks and Penny's brains).
  • Wil Wheaton getting an audition for Sharknado turned out to be true: he had a small role as an airline passenger in Sharknado 2: The Second One. Either this was purely a coincidence, or the writers added it because they already knew that Wheaton would be in the film.
  • In "The Anything Can Happen Recurrence", Bernadette states that Penny bought a watch for Leonard on his birthday with money she took out from his wallet. This action means that Penny should have seen the engagement ring before the actual proposal and wouldn't have been so surprised.
  • Leonard tells Penny that he has had the ring for a couple of years that dates back to the time he proposed to her while having sex.
  • An interesting (and circumstantial) piece of trivia. It's roughly about this point in the series that Amy begins, more and more, to distinguish between "monkeys" and "apes" when mentioning her experimental animals. Previously she never bothered with this and everything simian was just a monkey. Regardless of whether the experimental animal was a capuchin (true monkey) or an orang-utan (definitely and unambiguously a true ape). Only the more ignorant people, either consciously or carelessly (like Penny's director) persist in using the catch-all "monkeys". Leaving aside that an academic like Amy should be aware of the distinction anyway, this appears, perhaps, to be a tribute to one corner of the sci-fi/fantasy world where the distinction between "monkey" and "ape" is truly a life-or-death choice of words. In Sir Terry Pratchett's ''Discworld" series of fantasy novels, the Librarian of Unseen University - a place very like Caltech for oddball academics and seething rivalries - is a sentient orang-utan. Who takes direct and drastic action against anyone who cannot get the terminology right and calls him a "monkey". Now somebody in the Caltech gang (or the TBBT production crew) must have read the Discworld books, or at least the graphic novels. And they'd know that the surefire way of pressing an ape's Berserk Button is to call one a mere "monkey". Another shout-out to a widely-read and influential fantasy series?


Raj: Aren't you going to get 3-D glasses?
Sheldon: I brought my own. No sense of risking bridge-of-nose herpes.

Penny: There’s no reason why I shouldn't be the best bisexual go-go dancer slowly transforming into a killer gorilla that anyone has ever seen.
Leonard: I don’t know. The bisexual killer gorilla go-go dancer in “Schindler’s List” is tough to beat.

Penny: Oh my God, What a day.
Leonard: Can I get you anything?
Penny: No. I need to start making some smart decisions.
Leonard: With your career?
Penny: No. With my life.
Leonard: Like what?
Penny: I don’t know. We could get married.
Leonard: Come on, be serious.
Penny: I am.
Leonard: Why? Because I’m a smart decision?
Penny: Well, yeah.
Leonard: So I’m like a bran muffin.
Penny: Well, no. That’s not what I’m saying.
Leonard: No, it’s exactly what you’re saying. I’m the boring thing you’re choosing because I’m good for you.
Penny: What does it matter? The point is I’m choosing you.
Leonard: Well, it matters a lot. I don’t want to be a bran muffin. I want to be a Cinnabon, you know? A strawberry Pop Tart. Something you’re excited about even though it could give you diabetes.
Penny: Sweetie, you can be any pastry you want.
Leonard: No, no, no. It’s too late. I’m your bran muffin. Probably fat-free and good for your colon.
Penny: You know what? Forget it. I should've never brought it up.
Leonard: You know I want to marry you., but you’re only doing this because you got fired and you’re feeling sorry for yourself.
Penny: Okay, it may look that way, but getting fired from that movie was the best thing that could ever happen to me, okay? I finally realize I don't need to be famous or have some big career to be happy.
Leonard: Then what do you need?
Penny: You, you stupid Pop Tart.
Leonard: Oh. Then I guess I’m in.
Penny: Really? You guess you’re in?
Leonard: Not like “I guess I’m in:” Like “I guess…I’m IN!”
Penny: All right. Cool.
Leonard: So is that it? Are we engaged?
Penny: Yeah, I think so.
Leonard: All right.
Penny: What’s wrong?
Leonard: I’m not sure. Just feels a little anticlimactic.
Penny: Yeah, it kind of does, huh?
Leonard: Oh, I know. This might help.
Penny: Where did you get a ring?
Leonard: I've had it for a couple of years, not important. [Gets on knee.] Penny, will you marry me?
Penny: Oh, my God. Yes.
Leonard: This would have been so much more romantic if you didn't have monkey hair on your finger. [Couples hug.]

Director: And action.
Wil: Please don’t shut me out.
Penny: Go away. Just go away.
Wil: I swear, I will find a way to turn you back.
Penny: What gave you the right to mix my DNA with that of a killer gorilla?
Wil: I was trying to save your life.
Penny: Life? What life? Look at me I’m a monster! And now I have blood on my hands or paws. I don’t know.
Wil: You can’t give up. I love you.
Penny: I love you too. But I’m afraid I love killing more. Like, one day, I might actually try and kill you. [Ape screaming at him.]
Director: And cut. All right. All right, let’s set up for the next scene.
Penny: Actually, you know what? Can we do one more? I think I could do it better.
Director: Let’s just move on. No one cares.
Penny: Well, I care. I mean, look. IF we’re gonna do this, why not try and make it something we’re actually proud of?
Director: Look sweetie, this movie is garbage, but you should be happy about that, ‘cause if it was a good movie you wouldn't be in it.
Leonard: Whoa, whoa, hang on. There’s no need to insult her.
Director: And who are you?
Leonard: I’m her boyfriend.
Director: Isn't she too hot for you?
Leonard: A little, yeah.
Director: Well, boyfriend. Get off my set.
Penny: You can’t do that. He’s with me.
Director: You know what? You can get off my set too. You’re fired.
Penny: What? You can’t fire me. I’m the star. I’m the girl that goes bananas. It says so on the poster.
Director: Yeah, but we just shot the last scene where we see your face. So from now on, the star of the movie is whoever wears this.
Wil: Hey, if you’re gonna fire her, then you have to fire me too. [Everyone is in a bar.] Wow, that fell apart real fast.

Howard: The doctor says you need to get exercise!
Mrs. Wolowitz: I get plenty of exercise!
Howard: Crushing my will to live isn't exercise!

Mrs. Wolowitz: I told you this thing would kill me!

Sheldon: I know let’s go see the new Spiderman movie.
Amy: Sheldon, we’re talking about your friend’s mother. She got hurt.
Sheldon: I thought that subject had run its course so I changed it. It’s called reading the room, Amy.

Bernadette: You think we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

Sheldon: I’m sorry. I don’t have all the ingredients to make chai tea.
Raj: You don’t have to make me anything.
Sheldon: No, I do. You’re upset about Emily and you’re Indian. I need to make you chai tea. I have all the ingredients except cardamom seeds. You happen to have any on you?
Raj: Sorry, I left them in my turban.

Penny: You know, the only thing worse than being in a movie where they glue monkey hair to your ass is being fired from a movie where they glue monkey hair to your ass.

Penny: It’s easy for you to say. You used to be famous.
Wil: Penny, it’s not about being famous, it’s about the art, it’s about the passion you have for our craft. I have an audition for Sharknado 2.

Sheldon: Well, good night.
Raj: Don’t send me home. I can’t be alone right now.
Sheldon: That’s your problem. You can’t be alone.

Raj: Hey.
Emily: Thanks for letting me come over.
Raj: O.K. Please. Come in.
Emily: I just wanted to say how sorry I was about tonight and I wanted to make sure we’re OK.
Raj: Look, you and I haven’t made any commitments to each other.
Emily: I know. I just felt like I needed to explain. This guy did my last tattoo and he has been asking me out for months. I finally said yes just to get it over with.
Raj: It’s O.K.
Emily: Really?
Raj: Well, I mean, yeah, it freaked me out a little, but that's my issue, not yours.
Emily: Wow. IF I saw you out with another woman, I'd be pretty upset.
Raj: Thank you. Not for just being upset, but for believing that could happen.
Emily: Just so you know, I’m not seeing anyone else.
Raj: Well, me neither.
Emily: Okay.
Raj: Please. So you have tattoos?
Emily: Yeah.
Raj: I don’t. I have a hole in my belly button that may or may not have been a piercing.
Emily: That’s cool.
Raj: It’s a piercing. So how many tattoos?
Emily: One on my shoulder, one not on my shoulder and one REALLY not on my shoulder.
Raj: It’s been a long time since a girl’s “really not my shoulder”.
Emily: Well, how about you show me your piercing and I show you my tattoos? [Kiss.]
Raj: But before I take my shirt off I need about ten minutes to do some crunches.
