Penny: Hey. Step away from the bride.
Howard: (chuckles) Okay. I'll go back upstairs.
Bernadette: Get in the shower and then take those clothes and burn them.
Penny: Yeah, and all the rest of your clothes! Ah, worth a shot.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Penny: Sheldon, what did we say about being a nicer friend?
Leonard: Thank you.
Penny: Leonard, what did we say about being a gullible weeny?

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Georgie: After all my sacrifices, guess which kid my mom is the most proud of?
Leonard: If it makes you feel any better, my mom's most proud of Sheldon, too.

Georgie: Picking on him? Is that what he told you?
Leonard: Well, what about the time you threw away his Halloween costume?
Georgie: Well, yeah, 'cause he was gonna dress as some girl scientist.
Leonard: Madame Curie?
Georgie: Oh, I didn't know she was a madam.

Sheldon: Oh, maybe it's fine if she doesn't come to the wedding. I've got Amy now, and she can do everything a mom can do and more.
Leonard: Say that to her on the wedding night. Really spice things up.
