Katee: Thanks, Howard. Always nice to be part of your masturbatory fantasies.
Wolowitz: Come on, Katee. Don't make it sound so cheap.

Leonard: No, she was pretty clear about wanting to keep her options open.

Sheldon: Why do you have the Chinese character for "soup" tattooed on your right buttock?
Penny: It's not "soup," it's "courage."

Raj

Wolowitz: There are two not-unattractive middle school teachers.
Raj: Wonderful. How old are they?
Wolowitz: Fifty, fifty-five.
Raj: Woh, menopause, nature's birth control.

I should have asked for much more than a comic book and a robot.

Sheldon

"Sorry" doesn't make up for the fact that I had to make chicken and rice with this vegan guy! Do you know what vegan chicken and rice is? Rice!

Raj
