Penny: What else you hiding in there?
Sheldon: Wouldn't you like to know?
Penny: I would.
Sheldon: All right then. See, just my valuables. My passport, uh, my will-
Leonard: You have a will?
Sheldon: Yeah. My 1/18 scale Wil Wheaton action figure.

Raj: Hey, so what was Adam West like on the phone?
Leonard: Uh, nice guy. But it was a little weird to hear Batman say, "Don't ring the doorbell or my poodles will go crazy."

Raj: Hey, dude, you're killing me with Claire.
Zack: What are you talking about?
Raj: I mean, come on, look at you. You're classically handsome, you've got a swimmer's body. Next to you, I look like me.

Mike Rostenkowski: Bernie, you don't need to worry about me. But I don't want to see you miss out. Raising children was the most rewarding experience of my life.
Bernadette: Oh, please. Mom did everything. All you did was come home from work, sit on the couch and drink beer. How is that raising kids?
Mike Rostenkowski: This is really a conversation for husband and wife. I'm gonna go clean up, hit the road. If your mother asks, I was here till 10:00.

Howard: Look, uh I don't even think you can take this wall down 'cause it's load-bearing.
Raj: Well, it's easy to find out. Just go into the crawlspace under the house and check.
Howard: When is your visa up?

Bernadette: You guys can go in if you want.
Penny: No, we're a team. If you can't go in, we're not going in.
Amy: Then why are we drinking?
Penny: Okay, it's not like she's got the Christ child in there, all right?

Penny: Don't take advice from a man who threw his shoe at a crow.

Howard: You put up a good fight, lug nut, but you've met your match.

Leonard: Well, now instead of idolizing fictional characters, you can focus on the real people who are already in your life.
Sheldon: Those are very wise words.
Leonard: Thank you.
Sheldon: They'd just be so much more comforting if they came out of a television.

Raj: It's interesting your father didn't help around the house and Howard doesn't help, either, so in a way, Howard's not only like your father, but he's also like the child that you're afraid to have.
Howard: Why are you still here?
Raj: Fine, I'll leave. But it sounds like somebody needs a fresh diaper.

Bernadette: So I should probably explain why I kind of fibbed.
Howard: That would be nice.
Bernadette: I told my dad that you were the one who didn't want kids because I didn't want to disappoint him.
Howard: But you were okay throwing me under the bus?
Bernadette: Turns out yeah, I didn't think twice about it.

Howard: Hey, look! I found a seashell.
Mike Rostenkowski: Yeah, that's a rat skull.
Howard: (shrieks)
Mike Rostenkowski: Relax. There's enough droppings down here without you making more.

Sheldon: Not only is it signed to me but this is where he wiped his mouth. So we are currently in the presence of Leonard Nimoy's DNA.
Wil Wheaton: Um, doesn't Adam count as Leonard Nimoy's DNA?
Sheldon: No offense, but this is pure 100% Nimoy. Because of your mother, you're only 50%. Which isn't bad, but anything that you wipe your mouth on gets thrown away.

Penny: I can't believe Sheldon was gonna ask Amy to marry him.
Leonard: I know. I also can't believe he watched what we did on that couch and still sits on it.

Leonard: Come on, you pain in the ass!
Sheldon: That's me! Bye, Stuart.
Stuart: Wait! I'm a pain in the ass, too!
