Howard: Give me the bottle. I mean, it might be a little corny, but I say we pour one out for all the science homies who came before us.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Howard: I invented a game. Want to play?
Leonard: Sure.
Howard: It's called Emily or Cinnamon. I give you actual quotes I've heard Raj say, and you guess if he was talking to his girlfriend or his dog.

Bernadette: Does your mother call you every day at work to see if you had a healthy lunch?
Howard: My mother calls me every day at work to see if I had a healthy bowel movement.

Leonard: Oh, hi, you wanted to see me?
Ms. Davis: Yes. I wanted to talk to you about the e-mail you sent me last night.
Leonard: I sent you an e-mail?
Ms. Davis: You bet you did. "Hello. Shalom and aloha from the grave of Richard Feynman."
Leonard: (groans) Oh, it's coming back to me.
Ms. Davis: "Please accept the following retraction: I know I said physics is dead, but it is the opposite of dead. If anything, it is undead, like a zombie. Speaking of which, if Richard Feynman came back as a zombie, I would totally let him bite me."
Leonard: Any chance that's the end?
Ms. Davis: "I got bit by a squirrel once. I had to get rabies shots. I cried so much, my mother said 'don't be a baby'. In conclusion, physics is great. Squirrels suck, and someday, I'm gonna put my mom in a cheap nursing home. Yours truly, XOXO, Dr. Leonard Hofstadter."
Leonard: I-I-I can explain.
Ms. Davis: "P.S Can you come pick us up? The Uber driver won't open the door because Sheldon is covered in blue vomit."

Bernadette: At the office, I have two assistants! I don't even know their names. I just call them Thing 1 and Thing 2.
Amy: I don't have assistants.
Bernadette: I guess that's one of the benefits of being in the private sector. That and all the money I make!

Sheldon: Uh, One dumpling left. Who wants it?
Amy: Maybe you should offer it to the pregnant lady.
Sheldon: And that would be..?
Bernadette: Me, Sheldon. I'm obviously pregnant.
Sheldon: Well, you never said it to my face. And the last time I assumed a woman was pregnant, it did not go over well.
Penny: Yeah, I'm still mad at you.
Sheldon: You were drinking water instead of wine. What was I supposed to think?
