Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Professor Proton: Can I ask you a question?
Leonard: Yeah, sure.
Professor Proton: Why do you put up with Sheldon?
Leonard: Oh, you know because we're friends.
Professor Proton: Why?
Leonard: Wow, you ask really hard questions. Look, I know he can be aggravating, but what you have to remember is he's not doing it on purpose, it's just how he is. But he's also loyal and trustworthy and we have fun together.
Professor Proton: You know you're describing a dog?
Leonard: He did bite me once. But in his defense, I came up behind him while he was eating.
Professor Proton: They hate that.
Leonard: Sheldon is the smartest person I have met. He's a little broken and he needs me. And I guess I need him too.
Professor Proton: Why is that?
Leonard: Boy, you will not let this go, will you?

Sheldon: Arthur! Arthur, it's me, Sheldon Cooper.
Professor Proton: Trust me, I remember.

Professor Proton: Hold on, you have a girlfriend?
Amy: Yes, and I've heard so much about you. Hey look, we're wearing the orthopaedic shoes. I can't believe I dress like a celebrity.
Professor Proton: Okay, I get it now.

Amy: (Talking about Howard & Raj) They are going to have sex before Sheldon and I do. I knew it!

Sheldon: Look, a new topical antihistamine with lidocaine. Wow! I can't wait 'til I get a rash.

As Leonard, Sheldon and Amy shop for groceries, Sheldon is delighted to see Arthur Jeffries, Professor Proton, in line. Arthur has not certainly not forgotten about Sheldon. Later, in the university cafeteria, Howard asks if Raj wants to spend time with him on Friday as the girls are having girls' night at his place. When Raj says he's busy, Howard figures out he's going to girls' night. Leonard mentions he got an email from Professor Proton, asking him to take a look at a paper he wrote on nano-vacuum tubes. Sheldon finds it strange Arthur didn't contact him, so he checks his emails. He's disappointed to find two emails from Arthur, one asking for Leonard's email address and the other telling him he found it.

Back at the apartment, Sheldon complains to Amy about how he used to idolize Professor Proton. When Amy suggests perhaps Arthur didn't want Sheldon to read his paper as he finds him a bit much, Sheldon presses her to admit she thinks he's annoying. Meanwhile, the girls are making jewelry in Howard and Bernadette's apartment. Howard shows up and suggests the girls use his soldering iron to make better jewelry. Raj is not happy that the girls are excited by Howard's idea.

Sheldon wakes Professor Proton up in the middle of the night - well, seven thirty. Sheldon apologizes to Arthur for being annoying and asks him if he'd now consider working with him, instead of Leonard, on his paper. Arthur accepts Sheldon's apology but says he'd rather stick with Leonard. The next day, in Leonard's lab, he and Arthur are working together. Sheldon arrives with Bill Nye the Science Guy. Meanwhile, the girls are making jewelry in Penny's apartment. Raj is talking through his personal problems with the girls, until Howard shows up with tools for them to make even cooler jewelry.

Back at Leonard's lab, as he and Arthur continue their work, Arthur asks him why he's friends with Sheldon. Leonard describes Sheldon's good qualities, such as loyalty and trustworthiness, and admits they're both a bit broken and need each other. Leonard receives a text from Sheldon saying Bill Nye ditched him. Meanwhile, Raj has finally had enough of Howard intruding on girls' night. Raj tells him how he isn't comfortable sharing with him as he just makes jokes, so girls' night is the one place where he can open up about his feelings.

Arthur shows up at Leonard and Sheldon's apartment to see Sheldon. When Arthur asks him for his opinion on his paper, Sheldon says it would be an honour - although he's already hacked his email account and read it. Sheldon tells Arthur his paper was inspired and invites Arthur in for tea. Arthur initially rejects the invitation, but changes his mind when he sees Penny in the apartment. While Sheldon takes Arthur through his list of favorite Professor Proton episodes, Arthur wonders whether Penny has any single grandmothers. Elsewhere, Raj goes to Howard's to apologize for his behavior on girls' night.
