Bernadette: Hey. You got a minute?
Howard: Not really. Visigoths are kind of up my butt right now.
Bernadette: Pause the game, Howard.
Howard: "Howard?" Uh-oh. Make room, Visigoths.

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.

Wil Wheaton: Hey, Sheldon. This is Adam Nimoy.
Adam Nimoy: Nice to meet you.
Sheldon: Oh, it's nice to meet you. I admire your father's work very much.
It's not every day I get to meet someone whose life's journey began in my hero's scrotum.

Howard: May I say something?
Bernadette: Is it about how I can't have new wallpaper 'cause your dad left when you were little and your mom died?
Howard: Never mind.

Sheldon: As a child, when faced with a dilemma, my mother encouraged me to ask, "€œWhat would Jesus do?" The answer to that was always, "Love thy neighbor." But my neighbor had a dead tooth, so that wasn't going to happen.
But that's why I changed it to, "€œWhat would Spock do?"
Adam Nimoy: Did you find that helpful?
Sheldon: Yes. Oh, for example, three years ago when I discovered Penny was eating all my Pop-Tarts, instead of getting angry or vindictive, you know, I got a floor safe.
Penny: I knew I could smell 'em.
