Raj: Leonard and Howard don't have a flat; they went to the movies. Look! (walks over to Penny and Bernadette, and they both look at the text message Howard sent)
Bernadette:(at the same time) Son of a bitch.
Raj: You know what? I'm gonna let them know that I'm here with you, and that they're busted.
Penny: No, you know what? Don't, don't. Let's let them think they're getting away with it.
Bernadette:(grinning devilishly) Yeah, let's see how deep a hole they can dig for themselves.
Raj: Interesting. I mean, it's not testicles on a cyrostat, but I like it.
Sheldon: I’m sorry if you think less of me.
Amy: I don’t.
Sheldon: Really? ‘Cause every time I come in here, I think less of me.
Sheldon: Because I’m a fraud. No. I purport to be a man of the mind. I’ve been such a-a vocal champion of the Singularity, but how can I leave my body behind and become one with the Internet, when I never even thrown away a toothbrush?
