Raj: It's very simple. For breakfast, she has an egg-white frittata. Feel free to give her a choice of home fries or an English muffin, but not both. We're watching our weight. Uh, for dinner, something simple, a veal chop, some scampi, whatever you like.
Howard: Classy dog.
Raj: Yes. Also, don't forget to close the toilet or she'll drink out of it.

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

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?

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.
