Leonard: Are we done?
Raj: Not yet. This is fun.
Ooh, I know. I'd let her free my willy.

Howard: Leonard, wait.
Leonard: What?
Howard: I'd like to Spongebob her Squarepants.
Raj: Now we are done.

Leonard: Well, I got married recently.
Mandy: Oh, congratulations. To Sheldon?
Leonard: Ah, ha, never gets old.

Mandy: Maybe you should talk to a therapist about this.
Leonard: Too expensive.

Leonard: You'd think I'd be used to women withholding their love. My mother did. No matter how hard I tried, she just didn't have any interest in me.
Mandy: Imagine that.

Leonard: I wonder if that's why I have such a dysfunctional relationship with Sheldon. I had a dream the other night that I was in a cave, and I was nursing a baby. But the baby had Sheldon's head on it.
Mandy: And your wife is worried about me?

Raj: Hey, Leonard. When you're done, we came up with a bunch more.

Sheldon: And then the Czech Republic says to Slovakia, I don't think you understand how being broken up works.
Can you believe that? You'd think the Czech Republic would try to hold on to what it did, given it's not as young as it used to be. And I don't see any other countries lining up to invade its southern borders.

Amy: (watching Fun with Flags) I'm going to kill him.

Sheldon: But enough about the Czech Republic. Let's talk about the time Moldova made Romania a birthday cake, and Romania said it tasted good even though it didn't, and yet Romania got dumped. I'll pause here while you mull that one over. I know, right?

Leonard: Do you remember when you accused me of trying to sabotage our wedding?
Penny: Uh-huh.
Leonard: I've been thinking about it and you might be right. But the good news is I'm pretty sure I know why.
Penny: I'm listening.
Leonard: Penny, after all these years I still feel like maybe I don't deserve you.
Penny: Okay, that is the lamest excuse you could have possibly come up. But I get it.

Penny: Sometimes I worry you're going to wake up and leave me for someone more like you.
Leonard: I don't even understand why you're with someone like me. Why would I want to be with someone like me?
Penny: You know what I mean. And maybe the way I've been reacting was me sabotaging this, too.

Leonard: Well, how about we stop being so scared of losing each other, and just be together?
Penny: That sounds nice.
Leonard: Good. I've loved you from the moment we met and I will keep loving you until the end of time.
Penny: Oh my God, that is the most beautiful thing anyone's ever said to me.
Leonard: Yeah? That's because you're beautiful, and your beauty fills my heart with love and song.
Penny: Getting kind of cheesy, Leonard.
Leonard: You think that's cheesy? Buckle up.
(Leonard gets down on one knee)
Leonard: Penny Hofstadter, will you please stay married to me?
Penny: Oh dammit, you topped it.

Penny: Sheldon, I can't believe you got us a wedding gift.
Sheldon: I don't know why you're so surprised. I watch movies. I see what people do.
Leonard: What is this?
Sheldon: Plane tickets and hotel reservations for a weekend away in San Francisco.
Penny: That is so great!
Sheldon: Yeah, there's fisherman's wharf, and Alcatraz, and cable cars. We're gonna have so much fun.
Penny: We?
Sheldon: Is there a problem?
Penny: Uh, no, no. I just said "Weeee!"

Amy: How dare you go on the Internet and say mean things about me, and compare my genitalia to part of Czechoslovakia.
