Sheldon: Wonderful. Although I'm not sure how I feel about being used as a guinea pig.
Leonard: Well, when you get the machine, you can find out.

Leonard: Hey, great news. The TV I want will fit in the gaming room, and if I leave the curtains open, I can watch it from work.

Amy: Okay, I'm looking at the first picture.
Sheldon: You are happy?
Amy: Yes. I'm looking at puppies.
Sheldon: Aw. Somebody's ignoring their tiny needle teeth, but all right.

Leonard: I'm not saying you have to ask my permission, but you could have talked to me about it before you said it was okay.
Penny: Like you talked to me about your gaming room?
Leonard: Our gaming room! I was gonna put a scented candle in it.

Leonard: Stay out of this. You and your stupid machine started this fight!
Sheldon: (gasps) You are lucky that this feelings machine doesn't have feelings.

Sheldon: I thought I was getting better at it, but clearly I'm not.
Amy: Yes, you are. There have definitely been days when I was sad and you could tell.
Sheldon: Yeah, but that's shooting fish in a barrel. You're kind of a sad sack. I'm sorry, I shouldn't have said that. I'm just upset.
Amy: No, see, right there, you knew you hurt my feelings. And I'm proud of you - for reasons I'm sure have something to do with my father.

Raj: So did all of you go on to better relationships after me?
Lucy: Oh, yeah.
Emily: Without question.
Claire: Little before, actually.
Howard: (Interpreting for Emily) Oh, wow. Don't let him get away.
Raj: Wait. What did she say?
Howard: Uh, basically, she traded you for Bruce Wayne.

Sheldon: Uh, guys, it sounds like you're getting angry again.
Leonard: That's because we are.
Sheldon: Yes! I don't need an emotion machine! I am one!

Raj: Well, if you want to march in a fishnet crop top, you better lay off that dip.
Howard: If you didn't want me to eat it, why'd you put it out?
Raj: It was for the girls. They broke up with me. I don't care if they get fat.

Howard: Hey, is that any way to talk to your future husband?
Raj: Hey, I was being hypothetical, okay? I would never marry you.
Howard: Please. When you see the ring I pick out, you're gonna melt.
Raj: Yeah, right. Wait, is it rose gold? Actually, don't tell me. I want to be surprised.

Penny: So, did you wind up sending that machine back?
Sheldon: I did. You know, I'm not even sure how accurate it was. I took it to the train store, it said everyone was sad.

Sheldon: Hey, uh, Bernadette, let's test this theory. What do you think I'm feeling right now?
Bernadette: Let's see. You're better than us, a little bit sorry for us, but mostly glad you don't have to be us.
Sheldon: (To Howard) Keep filling this one with babies. She's good.

Penny: You guys ready to get crazy?
Amy: Well, the bra under here ain't beige.

Howard: Sheldon, we don't need to make this smaller. Your work is done. Go home.
Sheldon: I don't want to go home.
Leonard: Then go for a little walk.
Sheldon: Then what?
Leonard: Just keep walking.

Leonard: At least it's quiet when he takes bathroom breaks.
Howard: I know. That's why I keep refilling his water when he's not looking.
Leonard: You're kidding.
Howard: I don't care if we're in a drought, it's worth it.
