Howard: Hey Mike?
Mike Massimino: Yeah.
Howard: I changed my mind. I don't want to do this.
Mike: Good one.
Howard: Yeah, I'm a funny guy. I also have a hysterical bit planned for later where I pretend to cry through the whole launch.

Mike: That's ignition. I love this part.
Dimitri: Me, too.
Howard: I have strongly mixed feelings.

Amy: Stop it! Today is not about you, it's about Howard and Bernadette, and me!

Amy: Bernadette, I want to thank you for allowing me to be your maid of honor. I also want you to know that I will be happy to do it again if this marriage craps out.

Amy: I love his eidetic memory, it's so sexy. Sheldon, what are the ingredients in Pringles?
Sheldon: Dried potatoes, vegetable oil, corn flour, wheat starch, maltodextrin, salt, and my favorite ingredient of all, uniformity.
Amy: The uterus quivers, does it not?

Howard: Bernie, I have to go pick up my mother. I'll be right back.
Bernadette: Why can't she drive herself?
Howard: She doesn't want to sit in her dress and wrinkle it so I'm going to lay her down in the back of my neighbor's van.

Leonard: Where'd you get a beer?
Raj: From that happy young couple over there with all the tattoos. Beautiful story. They're in rival drug gangs, and they're getting married. Shh, no one can know.

Penny: I can't believe it. This whole time, a small part of me thought he was lying.

Sheldon: The need to find another human being to share one's life with has always puzzled me. Maybe because I'm so interesting all by myself. With that being said, may you find as much happiness with each other as I find on my own.

Bernadette: So, what do you say, Amy?
Amy: Can I wear my maid of honour dress?
Bernadette: Seriously? You're going to wear that thing to City Hall?
Amy: It's all I have left. You're going to take that from me, too?

Mr. Rostenkowski: Here you go.
Bernadette: "Here you go?" What am I, a football?
Mr. Rostenkowski: Like that guy could catch a football.

Howard: There's fuel leaking and we're still going to go?
Mike: Don't lose your Froot Loops, Froot Loops.
Dimitri: This happens a lot. Nine times out of ten, no problem.
Howard: What happens on the tenth time?
Dimitri: Problem.

Mrs. Wolowitz: You know what, I'll buy you All-Bran in case you get stopped up in outer space.

Howard: Ma, you want to move your chair over here so you can see?
Mrs. Wolowitz: I'm fine where I am. I don't want to fall off the roof.
Howard: You'll fall through the roof before you fall off it.

Sheldon: Thank you for the invitation, but I have to decline because it doesn't sound like something I'll enjoy.
Leonard: Come on, Sheldon, it'll be fun.
Sheldon: That's what you said about The Green Lantern movie. You were 114 minutes of wrong.
