Sheldon: Arthur.
Professor Proton: You-you know, we could we could also meet in-in a deli.
Sheldon: I'm sorry to say that I failed you. I tried to stop Wil Wheaton being Professor Proton, but I couldn't.
Professor Proton: See, now, that's-that's the kind of thing you could tell a fella over a pastrami sandwich.

Sheldon: I know why. You've come to me because you're my Obi-Wan.
Arthur: I'm not familiar with that. Is that an Internet?

Professor Proton: Oh, great, this again.

Professor Proton: Why isn't it ever Angie Dickinson's bedroom?

Sheldon: Until next week, this is Professor Proton saying, 01000010 01111001 01100101. That's "Bye" in ASCII binary, or good-binary.

Amy: Well, what was wrong with it? You know, did you find it borderline psychotic? I mean, I liked that about it, but you guys discuss.

Sheldon: You can't be Professor Proton. You're not a scientist.
Wil Wheaton: Well, I was never on a starship, but pretending I was bought me this house. And if I'd pretended a little longer, it would have a swimming pool.
