Professor Proton: Let me see if, if I have this straight. You, you two are, are physicists, and you, and you want me to do a children's science show?
Sheldon: Yes. And if there's time, take 12 pictures with us in seasonal clothing.
Professor Proton: You know, I'm a real scientist. I, I have a PhD from Cornell University.
Sheldon: Yeah, that's great. Did you bring your puppet?
Professor Proton: No, no. I, I hate that puppet.
Sheldon: Oh, no. How could anybody hate (in an exaggerated Italian accent) Gino the Neutrino? It's nice, huh? I got him for 20 bucks on eBay. (Italian accent) Including the shipping!
Professor Proton: I'm, I'm awake, right? Th, this is happening?

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?

Professor Proton: Okay, as, as I put the egg on top, and, and the flame goes out and, and, and the air pressure decreases in, in the flask, what do you think will happen?
Penny: I think I know.
Sheldon: It's gonna get sucked in. It's going to get sucked in.
Penny: Okay, I didn't know.
Sheldon: Yes!
Penny: See, I'm not a scientist like them.
Professor Proton: I, I figured that out.

Professor Proton: I'm having trouble with my pacemaker.
Leonard: I'll call for help.
Penny: Any chance we could plug it into the potato?
Professor Proton: No.

Howard: How'd you get him to come to your house?
Sheldon: As Professor Proton always says, there is no problem you can't solve if you use your noggin.
Leonard: And he wrote him a check.
Sheldon: Yeah, that too. A big check.
