Tam: Sheldon, come here.
Sheldon: Bazinga!

[After montage of classic The Big Bang Theory moments with Tam as Sheldon's roommate]
Sheldon: No, my life would've still been great.

Tam: I didn't mean to upset you. And I want you to know I'm really proud of everything you've done.
Sheldon: Thank you. It did work out for me. And I'm sorry that things didn't work out for you.
Tam: They did work out for me.
Sheldon: Oh, Tam, you don't need to be brave on my account.
Tam: I'm not. I have a great wife and amazing children. I'm very happy.
Sheldon: Brave, brave Tam.

Leonard: I'm glad you guys made up.
Sheldon: Well, I realized my life turned out great, and it's silly to hold a grudge.
Tam: And I had no idea we were fighting, so it was easy.

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.

Anu: [on the phone] Okay, I got you two seats to Hamilton tonight. Your tickets will be at the concierge desk. Of course. My pleasure. [to Bernadette and Penny] May I help you?
Bernadette: Yes, I'm here to pick up our Hamilton tickets.
Penny: Stop.

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.

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.

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: 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.

Leonard: I still can't believe Sheldon had a best friend we've never heard about.
Raj: Ooh, somebody's jealous.
Leonard: I'm not jealous.
Howard: Leonard, this is a safe space. It's okay to be vulnerable.
Leonard: All I'm saying is you know the timing of a fellow's bowel movements, you don't think there's a lot left to discover.

Howard: I wonder what Tam could have done.
Raj: Hmm. Well, if Sheldon doesn't want to talk about it, it's got to be pretty upsetting.
Howard: I have his brother George's number, he might know.
Leonard: Really? You have George's number?
Raj: So so jealous!

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: Oh, this is so nice.
Penny: Mm-hmm.
Bernadette: Maybe instead of introducing ourselves to Anu, we could just get a room, order some food and take a nap.
Penny: Yeah, I've fallen for that line before. It never leads to napping.
