Sheldon: And to think I idolized that man. And why? At the end of the day, he's just another Hollywood phoney.
Amy: Is it really worth getting upset about?
Sheldon: They say don't meet your heroes. Don't peek behind that curtain of fame and celebrity. Because if you do, you'll see them as they really are: degenerate carnival folk.

Amy: This is fun. I'm gonna feel like a vixen wearing jewellery that doesn't have a list of medications I'm allergic to.

Amy: So what tools did you bring?
Howard: Everything we need to make jewellery moulds. Here's some silver, a crucible, and an acetylene torch to melt it down.
Penny: Ooh, that looks fun.
Bernadette: Maybe you should master glue before you move onto fire.

Amy: I've never seen him (Sheldon) this happy before.
Leonard: That's because you've never seen him on "Restock the Medicine Cabinet" day.

Leonard: Dr. Jeffries, hello again. Leonard Hofstadter.
Professor Proton: Oh, right. I remember your girlfriend. *Looking around* Is she here?

Raj: There are just some things I feel more comfortable sharing with the girls. Because they won't make fun of me, or call me names, or ask me if my Koothrapanties are in a bunch.

Professor Proton: (To Penny) So, you have any single grandmothers?
Penny: Sorry, they're both married.
Professor Proton: Good. .... Happily?

Leonard: Okay, we're almost ready to go. Once we bond the wires, we can test the tubes.
Professor Proton: This is so exciting. I feel like I'm seventy-five again.

Raj: *Imitating Howard* My name is Howard. I can make your hair into diamonds. My mom is morbidly obese. Everyone love me.

Sheldon: Well, if you're hoping to get in touch with Bill Nye, I can't help you. I have been informed he is now Bill Nye, the Restraining Order Guy.

Professor Proton: I was thinking if it isn't too much trouble, I'd like to get your opinion about my paper.
Sheldon: Thank you, it would be an honor.
*Professor Proton hands Sheldon his paper*
Sheldon: Actually, I don't need that. I hacked into your email account and read it.
Professor Proton: What did you think?
Sheldon: First, I think the fact you use your birthday as a password is embarrassing.
Professor Proton: Thank you.
Sheldon: Second, I thought your paper was inspired.
Professor Proton: Well that means a lot to me.

Sheldon: Can I invite you in for tea?
Professor Proton: No, I really have to run .
*Penny walks in the room*
Penny: Hey Arthur, how are you?
Professor Proton: Well I guess one cup wouldn't hurt.

Leonard: Mr. Nye, hello. I'm sorry he got you involved in this nonsense.
Bill Nye: He told me I'd be speaking to a class.
Sheldon: No, I said you were teaching someone a lesson.

Sheldon: So what prescription are you getting filled?
Leonard: Sheldon!
Sheldon: No wait, I want to guess. Don't tell me.
Professor Proton: I wasn't going to tell you.

Sheldon: No, wait. I'm really good at this. Give me a hint. Does it involve difficulty initiating a stream of anything?
Professor Proton: Well, given my age, that's more than just a lucky guess.
