Sheldon: I'm sorry, I thought this delay was so you could watch Wheel of Fortune with your mother.
Howard: I am. She's just bleaching her mustache. Check it out. Hey, Ma! Before and After! Four words, 17 letters, two N's, one V.
Mrs. Wolowitz: (offscreen) Fanny pack of wolves.
Leonard: That's incredible.
Howard: Yeah, she's kind of a Wheel savant.

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.

Penny: Give my friend his stuff back.
Tod Zarnecki: I don't know what you're talking about.
Penny: Well then good news. Today's the day a girl's finally going to touch you in your little special place. *Kicks him in the groin*

Raj: Come on, dude, bros before ... my sister.

Sheldon: I've never said these words before, but good job, Howard.
