Raj: Wait, wait, wait. If Tam knows what he did, we can just ask him. He's gonna be on campus tomorrow showing his son around.
Leonard: Won't that make Sheldon mad?
Raj: Everything makes Sheldon mad.
Howard: Yeah. Look at his list. Jim Henson for, quote, "putting a terrifying, giant yellow bird on television and in my nightmares."

Bernadette: I'm pumping!
Penny: It's Penny.
Bernadette: Oh, come in.
Penny: I thought you were pumping.
Bernadette: I thought you were my boss.

Penny: Okay, listen, I'm really worried about this whole Raj thing.
Bernadette: I know, he's so desperate to get married, which is weird, because I can't imagine we make it look that great.
Penny: I know, right?

Penny: You know, if this woman's gonna be around, I think we should check her out a little. I looked online. She doesn't have an Instagram, which means she's either 80 or something's wrong with her.

Bernadette: Well, I could ask my dad. Maybe he can get some of his old cop buddies to do a background check on her.
Penny: Would he do that?
Bernadette: Of course. He's a retired cop who plays by his own rules. [on the phone] Hi, Daddy. No, everything's good. I just have a favor to ask. Yeah, so, my friend Raj is marrying this woman that he barely knows, and I wanted to see if you could use your connections to dig up any dirt on her. Uh-huh. Sure. Okay. Love you.
Penny: Is he in?
Bernadette: Absolutely not. He won't do it. It's totally illegal.
Penny: I thought you said he played by his own rules.
Bernadette: He does, but apparently, they're very similar to the actual rules.

Bernadette: So, are you actually engaged to this woman you just met?
Raj: Yeah.
Penny: Tell us the truth. Did she get you pregnant?

Raj: Guys, I need your help, okay? I'm trying to buy her engagement ring. What do you think of this? Do you think she'll like this one?
Bernadette: Well, it's hard to say, not knowing much about her. Does she have fingers?
Raj: Yes, she has ten fingers and ten toes. Probably. I'll get back to you after I see her in sandals.

Amy: Hey, did you guys know that Sheldon had a best friend growing up named Tam?
Leonard: Was that the imaginary talking koala?
Amy: No. He's a real person who apparently betrayed him.
Leonard: Yeah, so did the koala.

Howard: Wow. I wonder what that guy could've done to make Sheldon not talk to him for 20 years.
Leonard: I wonder if it'd work a second time.

Amy: Hey, whatcha doing?
Sheldon: Improving our wedding photos.
Amy: Oh, that's nice. Wait, I'm still in them, right?

Sheldon: Of course.And not only you. I've added some guests who couldn't be there.
Amy: Who's that next to my father?
Sheldon: The Wright brothers.
Amy: And why are they at our wedding?
Sheldon: Orville, because I admire him; Wilbur, because he was Orville's plus-one.

Amy: Oh. You got an e-mail from someone named Tam.
Sheldon: Tam? What does he want?
Amy: Uh, looks like he's coming to give his son a tour of Caltech. He's hoping you guys can meet up.
Sheldon: (scoffs) He would like that, wouldn't he?
Amy: Well, that is the gist of the e-mail.

Amy: Who's Tam?
Sheldon: He was my best friend in the whole world growing up.
Amy: Really? Why have I never heard you mention him before?
Sheldon: Oh, of course I have. I'm sure I've mentioned him, like, five times this week.
Amy: I don't think you have.
Sheldon: Tam! Tam! Tam! Tam! Tam! There, it's only Thursday.
Amy: I didn't just drink the crazy milk, I bought the crazy cow.

Bernadette: Hey, Howard.
Howard: Yeah?
Bernadette: It looks like you could crack a walnut in those glutes.
Howard: I can't. I tried.

Penny: Hey.
Leonard: Hey.
Penny: I made you dinner. Your favorite: In-N-Out Burger out of the wrapper on a plate.
