Howard: I've worked with Hawking. He's got a great sense of humor. And I think he'd like it.
Bernadette: Okay, call him and show him. I dare you.
Howard: I have no problem calling him.
Bernadette: Fine, then do it.
Howard: Fine, I will.
Bernadette: While you're bothering the world's most famous scientist, be sure to show him how funny he looks getting stuck under our dishwasher.

Howard: You busy? There's somebody out here who wants to meet you.
Bernadette: Who is it?
Howard: Say hello to everybody's little friend, remote control Stephen Hawking!
Bernadette: Where did you get that?
Howard: I found him in an old box.
Bernadette: Why would you buy it?
Howard: I didn't buy it. I made it.
Bernadette: Last question. What is wrong with you?

Leonard: It's always fun watching him read someone else's work.
*Sheldon grimaces as he's reading Bert's paper*
Penny: It's like scrolling through the emojis on my phone.

Amy: Sheldon, it's foolish to be angry that Bert's work has merit.
Sheldon: Yeah, well I am angry! And you telling me not to be angry makes me angry! And do you know how hearing myself say the word angry over and over makes me feel?
Penny: (raises her hand) Ooh, angry?
Leonard: What are you doing?
Penny: I knew the answer. I got excited.

Leonard: Hey, buddy, why don't we go for a walk, so you can calm down.
Sheldon: That's a good idea. I guess everyone's having them now.
Leonard: Hey, I'm trying to help you.
Sheldon: Fine. You can walk ahead of me and scare off the pigeons.
Leonard: (To the girls) You just wave your arms a little and they fly away, it's not--

Howard: Okay, Raj, I'm gonna show you something. Now, one of us thinks it's offensive. The other thinks it's hilarious and a great idea. But, I'm not going to tell you who likes it.
(Howard demonstrates Remote Control Stephen Hawking)
Raj: This is tough. But I'm going to say it's the guy who shows me YouTube videos of people getting hit in the nuts.

Sheldon: Leonard, I'm having a primal urge to throw this rock.
Leonard: Do it. Visualize it as your anger and toss it out of your life.
Sheldon: Perhaps I will. This rock encapsulates all my negative emotions. I will cast you far away. Feel free to take out a pigeon while you're at it.
Leonard: Let it fly.

Amy: You know, Sheldon, instead of fixating on what Bert has, you should appreciate all of the good things in your life. You've got love, you're in good health, you've got a roof over your head.
Sheldon: Yeah, but you've got all those things, and no one's lining up to be you.
Amy: Anybody else want to try? I'm gonna go make some more tea and question my life choices.

Amy: What's up?
Howard: I'm conducting a quick survey. Do you think this respectful and loving tribute to a great man is in poor taste? (Howard rolls out Remote Control Stephen Hawking)
Amy: Yep.

Howard: Do you think this is in poor taste?
Leonard: Does it spin around and do tricks?
Howard: Yeah!
Leonard: Then yeah.

Amy: I can't believe you head-butted a water fountain.
Sheldon: No, I went to punch the water fountain, slipped in water in front of the water fountain, and hit my head on the water fountain.

Sheldon: Sorry I'm moving slowly.
Leonard: Oh, I don't mind. If you pull a butterscotch out of your pocket, it would be like I'm walking with my grandma.

Sheldon: A plaque? Nobody wants to see this.
Leonard: Well, change "plaque" to "mixed-race couple" and you are my grandma.

Sheldon: I was hoping by admitting my weakness to you, I'd somehow be unburdened.
Bert: Is it working?
Sheldon: No. Now that you know my weakness, I hate you more than ever.

Bert: Sheldon wait. You know, you've got a lot to be happy about. You're at the top of your field, you have a great girlfriend.
Sheldon: Yes! That's right! I have Amy! In the past, you've professed feelings for her. Does it eat you up inside that I have her and you don't?
Bert: It used to. But now that I'm rich and successful, I think I can do better.
