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

Wolowitz: So, what are we watching? Sex in the City, yikes!
Penny: Hey, I happen to love this movie.
Wolowitz: Fine, let's watch it. Maybe all our periods will synchronize

Wolowitz: Raj, I'm gonna really miss you.
Raj: Will you come visit me?
Wolowitz: 17 hours is a really long flight, how about we meet halfway?
Raj: Halfway is 600 miles off the coast of Japan
Wolowitz: We'll skype

Raj: When we tell the story, let's end it differently
Wolowitz: What are you thinking? A big musical number?

Yes, she's pushy, and yes, he's whipped, but that's not the expression

Wolowitz [to Raj]

They're called tattoo sleeves. I bought them online. Raj got a set too. Put them on, have sex with some freaky girl with her business pierced and I can take them off and still be buried in a Jewish cemetery

Raj: What happened?
Sheldon: Obviously another carnal fiasco with the 'Shiksee' goddess.
Howard: Shiksa. Shik-Sa.
Sheldon: Forgive me. Yiddish was not spoken in East Texas. And if it was, it wasn't spoken for long.

Wolowitz: Sex is never the way I dreamed it was going to be.
Raj: Because in your dreams, you're a horse from the waist down.

you're missing the point, a Shiksa goddess is not an actual goddess, we prey on them, not to them

Leonard: Will you take that stupid red hat off?
Wolowitz: No, I want to blend in
Raj: To what? Toy story?

Leonard: I don't want to go to Texas
Wolowitz: Alright and I do? My people already crossed the desert once. We're done

Wolowitz [about his mustache]: I call it the Clooney
Raj: I call it the Mario and Luigi, but whatever

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
