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.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

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.

Sheldon: Would you like some aloe vera? 'cause you just got burned.

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