Raj: Yeah, I was on my way to tell Howard, and then I remembered I wasn't speaking to him, so I came over here.
Leonard: Mm, don't you think it's time you two made up?
Raj: No. No, actually. I don't need his negative energy in my life right now. Standing up to him was-was hard, but it made me realize that I can do anything. And, yeah, it's a little sad, but, you know, life is all about-
Penny: (cork pops) Uh, sorry. I thought you were wrapping things up.

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

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?

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

Sheldon: I mean, it's not that I think we're living in sin, but I do like the idea that our next act of intimacy will be a legal requirement.

Amy: Maybe we should just get married at City Hall and forget about everything else.
Sheldon: City Hall, hmm. I do like metal detectors and the sound of permits being denied.

Sheldon: Neither of them will be the actual cake. I'm just using it as a bargaining chip to get Amy to agree to the whole wedding party getting rings and us getting one ring to rule them all.
Howard: I forget, which mental hospital are you guys registered at?
