  • Quotes (5)

    • Sheldon: (to Leonard) Do you really think death threats are an appropriate way to begin this conversation? Sometimes your lack of social skills astonishes me.

    • Raj: Hey, Leonard? Leonard: Yeah? Raj: I haven't had sex in a year. Leonard: Where are you going with this, Raj?

    • Sheldon: I'm glad we're still friends. Penny: Really? Sheldon: Oh, yes. It was a lot of work to accommodate you in my life. I'd hate for that effort to have been in vain.

    • Raj: Hey, do you think the elastic woman in The Incredibles needs to use birth control, or can she just be a diaphragm? Howard: Well, that's it, we're officially out of things to talk about.

    • Sheldon: Howard made it very clear that my allegiance should be to male comrades before women who sell their bodies for money. Leonard: Is it possible he said, "Bros before hos?" Sheldon: Yes, but I rephrased it to avoid offending the hos.
