Sheldon: You know, I felt the same way about the spork. Uh, solids and liquids handled by one utensil? That'll never work. Spoiler: works.

Bernadette: This is ridiculous. The doctor knows what the baby is, the ultrasound tech knows, Raj knows, his Grey's Anatomy online fan group probably knows.

Leonard: You know what? There is one thing I would like.
Sheldon: Yeah, take whatever you want.
Leonard: I would like to keep the official flag of our apartment.
Sheldon: But you don't even like flags.
Leonard: Yeah, I like this one.
Sheldon: But I designed it.
Leonard: But you made me order it because you were "too well-known" in the flag community and they'd jack up the price.
Sheldon: But you don't even understand its symbolism.
Leonard: Oh, I do. The-the field of blue represents you being miserable, and the lion sticking its tongue out means I'm happy about it.

Leonard: Oh, it's just nice to be with people who are happy to have me around. Isn't that right, Halley?
*Halley starts crying*
Howard: Well, at least someone had the courage to say it.

Amy: There are a lot of memories wrapped up in that room. For me, too. The first time you told me you loved me was in that room.
Sheldon: Wrong. We were standing outside my room in the hallway.
Amy: And there is the love of which I speak.

Leonard: Okay, so this is the main Comic-Con floor. It's where all the vendors and exhibits are.
Penny: Wow, that is a lot of people jammed in there.
Leonard: I know. Sometimes Howard wears a striped shirt so we can play "Where's Wolowitz?"

Raj: I'd love a personal trainer. I haven't seen my abs since they opened a Shake Shack on my drive home.

Raj: It looks like a map from Dungeons & Dragons.
Howard: Mm. Except the creature in the crib is a level-nine poop monster.

Amy: What are you looking at?
Sheldon: Comments from our Behind the Flags retrospective. Get this, people are calling it "the longest one yet".

Leonard: It's not just Howard and Bernadette. I mean, look how far we've all come.
Penny: Hmm.
Stuart: You two got married.
Amy: Sheldon and I are living together.
Sheldon: But if my mom asks, we have bunk beds.
Leonard: Penny was a struggling actress when we met, and now she's a successful pharmaceutical rep.
Penny: Okay, you don't have to say "struggling" every time. You can just say actress.
Stuart: Howard went to space.
Amy: Bernadette got her doctorate.
Leonard: Sheldon, Howard and I are working with the government on our quantum gyroscope.
Amy: We've all come a long way. There's a lot to be proud of.

Leonard: First thing tomorrow morning, we're back at it.
Raj: Without me.
Sheldon: I hope his character doesn't make it into the movie; he's kind of a bummer.

Raj: I can't believe Penny's gonna get to go, and I'm not.
Sheldon: You can always watch the panels online. Oh, boy, we do say that a lot.
Stuart: "Panels." Just wanted to be included.

Penny: See, that wasn't so bad. He even picked up the check.
Leonard: Yeah. Although, when he was trying to figure out the tip, I'm pretty sure I saw smoke coming out of his ears.

Bernadette: It's okay, I'm just being emotional about this. Can you not tell Howard?
Stuart: Well, don't you think it'd be healthier if you told him what's going on with you?
Bernadette: Don't you think it'd be healthier if you had your own apartment, grown man?
Stuart: Your secret is safe with me.

Amy: His mother warned me. Everybody warned me. Actually, he warned me.
