Penny: Oh, my God, you’re about to jibber jabber about jibber jabber.

Penny: We can't keep explaining everything. Read that book we gave you.

Sheldon: Just the latest copy of Applied Particle Physics Quarterly.
Penny: Oh, you know, that is so weird that yours came and mine didn't.

Penny: I love him, but if he's broken, let's not get a new one.

Penny: Amy is right, I do want to fling my poop at her.

Leonard: You know deep down inside, Howard's a nice guy.
Penny: The problem isn't what's on the inside. It's the creepy candy coating.

Sheldon: I lost this to Wolowitz in an ill-conceived cricket wager.
Penny: What, do they have Wii Cricket now? Well, that can't be very popular.

Penny: Hey Leonard, what's up with Dr Wackadoodle?

Raj: I can't believe Sheldon gave this up.
Leonard: I know. We're gonna have so much more fun than him.
Bernadette: No, they're not.
Penny: Knowing them, they will.

Penny: Leonard, you're looking for a way to sleep with both women and have everybody be happy about it.
Leonard: Now we're getting somewhere.
Penny: What does your gut tell you?
Leonard: Go ask Penny; she'll know what to do.

Penny: Um, you know it's kinda early. Do you wanna maybe come in for some coffee or something?
Stuart: Oh gee, its a little late for coffee isn't it?
Penny: Aw, you think coffee means coffee. That is so sweet.

Leonard: Okay, uh, how do I put this? Um, are you familiar with Darwin's observation of the finches in the Galapagos Islands?
Penny: Did they make a movie about it?
Leonard: No.
Penny: Then no.

Leonard: They've been in there for like half an hour.
Penny: Yeah, for future reference that's a while.

Penny: Okay, I understand everyone's a little tense today, so I am just gonna get to the important stuff. Leonard, standing here with you in front of our family and friends is bringing up a lot of feelings. Like what a good idea it was to elope the first time. But also how incredibly happy you make me. Thank you for marrying me. Hopefully for the last time.

Sheldon: The thing about tomatoes, I think you will really enjoy this, is that they are shelved with the vegetables but they are technically a fruit.
Penny: Interesting.
Sheldon: Isn't it!
Penny: No, I mean what you find enjoyable.
