Mrs. Fowler: I'm surprised Amy didn't pick us up.
Penny: Oh, well, you know, she's pretty busy the day before her wedding.
Mrs. Fowler: Too busy for her mother? She used to be such a devoted daughter. Now she's just waiting for me to die so she can get my china.

Mary: You'll have to excuse her. She's just pregnant and hormonal.
Raj: Oh, yeah, congratulations on baby number two.
Missy: Yeah. Whoopie.

Mary: Her husband would be here, but he stayed home to watch their older son, so e-everything's fine!
Missy: Stop it. We're separated.
Raj: You don't say?

Mark Hamill: Anyway, thanks so much. I-I want to give you a reward for finding him.
Howard: (chuckles) Oh, no, I couldn't take your money. It's just an honor to meet you.
Mark Hamill: No. No, please. You don't know what this dog means to me, and I thought he was gone for good. Please? There must be something I can do for you. Anything.
Howard: Oh, you're gonna regret that.

Raj: W-What is he doing here?
Howard: I found his dog and guilted him into officiating the wedding. Don't tell Sheldon. It's a surprise.
Raj: Wait, I-I thought Wil was officiating the wedding.
Howard: Yeah, so did he.
Raj: How did he take the news?
Howard: I'll let you know.

Leonard: Everyone's waiting. What are you guys doing?
Amy: Super asymmetry.
Leonard: Super asymmetry? Is that a thing?
Sheldon: We're inventing it right now.
Leonard: Don't you think this can wait until - Hold on. This is interesting.
