Sheldon: I couldn't sleep.
Penny: I told you those Walking Dead pillows were a bad idea.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Raj: We have to go over some ground rules about Emily.
Howard: Like when it turns out she's made of rubber, I don't say anything?
Raj: She's very real.
Howard: That's what it says on the box. Right next to dishwasher safe.

Bernadette: I'm excited to meet Emily.
Howard: I just hope he doesn't blow it.
Bernadette: Why would you say that?
Howard: Because he's Raj. That's his thing. Beckham can bend it. Ralph can wreck it. Raj can blow it.

Sheldon: (on Stephen Hawking's voice mail) I kiss girls now.
