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

Sheldon: Remarkable. In just under a half hour, 200 metric tons of fuel will ignite in a controlled explosion right beneath Howard's keister. And all from a country whose entire contribution to the global economy has been Tetris and mail-order brides.

Leonard: There's Howard's rocket, live from Kazakhstan.
Bernadette: Oh, God, I'm so nervous. I don't think I can watch.
Raj: Youre nervous? I've been stress-eating for four days. Look at me. I'm wearing my fat pants.

Raj: I keep telling you, if I wasn't an astrophysicist, I would have been a party planner. It was always a coin flip.

Raj: Howard and Bernadette, the five of us stand before you as your friends and newly ordained ministers.
Mrs. Wolowitz: Louder!
Bernadette: They all got ordained. They're all marrying us. It's adorable. If you want to hear come closer.

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.

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.

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.

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

Penny: Okay, I'll go. Howard and Bernadette, I know you two planned on getting married in a big fancy wedding, but when you're in love, it doesn't matter where or how these things happen. It just matters that you have each other.
Leonard: Hmm.
Penny: Problem?
Leonard: No.
Sheldon: I think the Reverend Hofstadter is making an ironic connection between your statement about love and your rejection of his proposal in the bedroom.
Penny: Oh, grow up.

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.

Bernadette: I can't believe we're not going to get married.
Amy: Excuse me, I'm going to go see if the couple at the front of the line needs a maid of honor.

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: 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.

Bernadette: Howard Joel Wolowitz, like you, this is going to be short and sweet. I love you with all my heart and soul and promise to be with you forever.
Howard: Bernadette Maryann Rostenkowski...
Mrs. Wolowitz: Speak up!
Howard: Hey, from now on, she's the only women who can yell at me!
