- Episode transcript 
- Jesse Schedeen of IGN - "The Viewing Party Combustion" had a good thing going for a while, blending humor with a little deep insight into the core character relationships that drive the series. Sadly, this show has a habit of finding quick and lazy resolutions to its conflicts, and this episode was no exception. The characters weren't forced to work through their differences and patch things up. Instead, Howard's medical emergency brought a swift end to the civil war. Nothing actually felt resolved, and it's not clear if we'll see this conflict renew in future episodes or if one evening of complaining was all the catharsis these characters needed. There was another flaw with this episode that bears mention. Raj has become insufferable lately. His ongoing relationship drama with Emily and Claire has managed to bring out the worst in Raj. His constant bragging about dating two women was obnoxious and repetitive, to say the least. To be fair, it was certainly easy to understand why Howard would need a break from his best friend, and it did lead to an amusing moment where he mocked Raj with a dead-on impression. 
- IMDb user reviews 
- This is the second time Howard has had an allergic reaction to nuts, the first was in "The Peanut Reaction" (S1E16), and the first time Penny and Amy are present to watch Howard deal with it.
- Penny knew enough about comic books to stump Sheldon and send him away.
- Raj's bragging about dating two women to annoy Howard could be his revenge on Howard for seeing Suicide Squad without him, then texting Raj to mock him about it, and promise to spoil the film for him.
- Howard had his annoying and obnoxious moments in The Holographic Excitation. Leonard and Sheldon even hypothesize that Howard would connect his trip into outer space with any subject and tested their theory by bringing up topics like lemons to which Howard compared to the rocket used on his space trip.
- Third episode (after The Celebration Experimentation) where all of the main characters (excluding Emily) share a scene together.
- This episode aired three days before the Season 6 Premiere of Game of Thrones. This indicated that the episode of Game of Thrones that the gang was gathering to see was the Season 6 Premiere of Game of Thrones "The Red Woman".
- When the gang separates to two apartments, Leonard complains that Sheldon always spoils the episodes by mentioning details from the books, like how Sheldon reveals that Bran Stark is in a forest with tree people. However, this is no longer the case, as the show has now caught up to the books, meaning that the books will no longer spoil the show. Sheldon even points this out to Stuart, claiming that he's upset at George R.R. Martin because there's no new books for Sheldon to spoil to Leonard. This is a reference to many fans frustration at Martin for the long delay in releasing the 6th book in the series, The Winds of Winter.
- Sheldon: I have a question about Batman. Batman is a man who dresses up like a bat. Man-bat is a part man, part bat hybrid. If Man-Bat dressed up as a man to fight crime, would he be Man-Batman?
- Sheldon: What, why did you get a party sub?
- Leonard: People are coming over; it looked fun.
- Sheldon: Well, we’re only watching Game of Thrones. A party sub implies it’s a party.
- Leonard: Your attendance implies it’s not.
- Sheldon: I like a party as much as the next man, as long as the next man doesn’t like a party.
- Raj: But, dude, you’re so lucky. Getting to stay home at night with the woman you love.
- Howard: I guess I am lucky.
- Raj: You are, because dating two women, I mean, I can’t even remember the last time I slept in my own apartment. I wake up and I’m like: “Am I at Claire’s or am I at Emily’s?” Is there a third girl I’ve forgotten about? Like… Where am I?
- Amy: Well, I get why he’s annoyed.
- Sheldon: Well, then you don’t understand what’s happening. See. Leonard refused to participate in a mandatory quarterly roommate agreement meeting. This is what a generation raise on Bart Simpson looks like.
- Leonard: You love the Simpsons.
- Sheldon: I love Lisa Simpson.
- Amy: Well, I know how he feels. I never enjoyed our Relationship Agreement meetings.
- Sheldon: Wait. You were pretending?
- Amy: Sorry.
- Sheldon: No! I don’t believe you. I could tell.
- Amy: (Sexily) Oh, Sheldon. I never thought re-filing a matter in a standing subcommittee could be so fascinating.
- Raj: Did Amy make her spinach dip?
- Sheldon: She did.
- Howard: And I'm gonna enjoy it all!
- Leonard: I don’t know how you put up with it. He’s impossible. I mean holding a meeting to decide what breakfast cereal we should buy.
- Howard: Yeah. Cap’n Crunch with Crunch Berries., move on.
- Leonard: Anyway, Amy, thank you for sticking up for me.
- Amy: Oh, I honestly couldn’t care less.
- Leonard: Sorry.
- Amy: Well, I just took your side ‘cause sometimes I get annoyed at how close Sheldon and Penny are.
- Leonard: They argue all the time. They aren't that close.
- Amy: Who's always comforting him when he's upset?
- Leonard: Penny, but...
- Amy: Who's the only one who can make him take his medicine when he's sick?
- Leonard: I try to hide it in his peanut butter, but he spits it out.
