  • Quotes (12)

    • Sheldon: I'm uncomfortable having been included in your lie to Penny. Leonard: What was I supposed to say? Sheldon: You could have told her the truth. Leonard: That would have hurt her feelings. Sheldon: Is that a relevant factor? Leonard: Yes. Sheldon: Then I suppose you could have agreed to go. Leonard: And what would I have said afterwards? Sheldon: I would suggest something to the effect of, 'singing is neither an appropriate vocation nor avocation for you, and if you disagree I'd recommend you have a CAT scan to look for a tumor pressing on the cognitive processing centers of your brain.'

    • Sheldon: (Knocking on Penny's door early in the morning.) Penny, Penny, Penny... (Penny opens the door) Sheldon: Good morning. Penny: Do you have any idea what time it is? Sheldon: Of course I do, my watch is linked to the atomic clock in Boulder, Colorado. It's accurate to one-tenth of a second, but as I'm saying this it occurs to me once again your question may have been rhetorical.

    • Leonard: How long is [Toby/Leo] going to stay here? Sheldon: He's a homeless drug addict, Leonard. Where's he going to go? Boy, you have a lot to learn about lying.

    • Sheldon: Artificial intelligences do not have teen fetishes.

    • Leonard: Penny, say hello to Leo. Penny: Hi, Leo. How are you feeling? Toby: Have you ever woken up in a flea-bag motel, covered in your own vomit, next to a transsexual prostitute? Penny: No. Toby: Then don't ask me how I'm feeling.
