As soon as we get home, I want to have coitus with Amy. Okay, she can't hear.

Sheldon: Sherlock Holmes always says when you eliminate the impossible, whatever remains, however improbable, must be the truth. Now, have-have you tried doing that?
Officer Hernandez: Nope.
Sheldon: Well, maybe you should. Th-th-there's lots of books called "Sherlock Holmes" and there's no books called "Officer Hernandez."

Now, typically I wear pajamas, but I recently adopted a hobo lifestyle and pajamas are the sleep-pants of the Man. I'll have you know, Mahatma Gandhi wore no pants and a nation rallied behind him!

Excuse me. Is it at all possible that you're knitting a pair of pants?

Leonard: Sheldon...
Sheldon: Yes?
Leonard: I'm gonna miss you.
Sheldon: Of course you are.
Leonard: He just made that easier.

Penny: He'll be okay. You taught him well, Padawan.
Sheldon: Good Lord! Padawan's the student,
not the teacher.
Penny: Seriously, let him go.

Leonard: So a few things don't go your way and your best decision is to ride the rails like a hobo?
Sheldon: I suppose it is. Except I have a credit card. And I refuse to carry my laptop at the end of a stick. And I'd sooner die than eat beans out of a can.

I do not accept this. Everything is changing and I hate it. It stops now.

Amy: Maybe you'll love living alone.
Sheldon: I don't know. Perhaps.
Amy: And if it turns out you don't ... you and I could live together.
Sheldon: You and... Oh, sure. And while we're at it, why don't we get engaged, too? Why don't we get a little house, start a family? Enjoy our sunset years together? Do you hear yourself, woman?!
Amy: Sheldon, it was just a thought.
Sheldon: No. Here's a thought. You're not moving in, Leonard's not moving out, everything stays exactly the way it is.

Sheldon: Move across the hall?! Did you take a marijuana?!
Leonard: No, I did not.
Sheldon: Did you get hit on the head with a coconut?
Leonard: No.
Sheldon: Well, then, I'm all out of guesses.

Sheldon: She's spent many nights here, and you're worried about preserving the myth of her virginity before the wedding.
Leonard: I'm not.
Sheldon: Good, because not only has that ship sailed, if it hit an iceberg, countless men would perish.

Sheldon: I don't have all the ingredients to make chai tea.
Raj: You don't have to make me anything.
Sheldon: No, I do. You're upset about Emily and you're Indian. I need to make you chai tea. Now, I have all the ingredients except cardamom seeds. Do you happen to have any on you?
Raj: Sorry, I left them in my turban.
Sheldon: Oh, I'll make English breakfast tea. They destroyed your culture. That's close enough.

TBBT Quotes

Mrs. Cooper: Shelly! I'm so glad you're here!
Sheldon: I saw you having naked sex.

You can't ruin a friendship with sex that's like trying to ruin ice cream with chocolate sprinkles.
