Howard: 1. I lost my virginity to my cousin, Jeanie. 2. It was my Uncle Murray's funeral, we were all back at my Aunt Barbara's house. Our eyes locked over the pickled herring. We never meant for it to happen. 3. To this day, I can't look at pickled herring without being aroused and ashamed. Oh, cousin Jeanie.

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.

Josh: So, I have to ask, was the robot sexy?
Howard: It was actually just a mechanical hand.
Josh: 'Cause that's all you need, right?
Howard: You are my brother.

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Raj: If I could speak the language of rabbits, they would be amazed, and I would be their king.
Leonard: I hate my name. It has 'nerd' in it. 'Len. Nerd.'
Wolowitz: I lost my virginity to my cousin Jeanie.
Raj: I would be kind to my rabbit subjects. At first.

Wolowitz: You're such a douche
Raj: Who cares? You slept with your cousin!

Sheldon: Now remember, you were given powerful pain medication and a muscle relaxer, so don't operate heavy machinery, and try not to choke on your own drool. [goes to leave] Penny: Wait! You have to help me get into bed. [laughs] "Sheldon has to help me get into bed". Bet you thought I'd never say that!
Sheldon: Yes. Charmed. Your drug-addled candor knows no bounds. [helps Penny into bed]
Penny: You know people think you are this weird robot man who's so annoying all the time and you totally are. But then it's like that movie Wall-E at the end. You're so full of love and you can save a plant and get fat people out of their floaty chairs.
Sheldon: That's a fairly labored metaphor but I appreciate the sentiment behind it.
