Raj: Did you go to your prom?
Sheldon: No. I had a date with a proper education. Instead of a tuxedo, I dressed myself in good habits. Instead of spiked punch, I enjoyed the intoxicating flavor of knowledge. Instead of dancing in a gym, I shook my bootie to the seductive rhythms-
Penny: Okay, okay.
Sheldon: -of AP calculus.

Sheldon: I ordered it before you had surgery. It's the urn I was going to put you in.
Penny: Okay, that's morbid. Send it back.
Sheldon: I can't send it back. I had it engraved. "Here lie the ashes of Leonard Hofstadter. He thought he was right, but his roommate knew better."

Penny: Wow, it looks really pretty in here.
Stuart: Yeah, turns out half a dozen Menorahs really sets a mood.

Howard: Settle this. Those little animated pictures on the Internet, are they called "gifs" or "jifs"?
Leonard: Well, the G stands for "graphics." That's a hard G, so I'd say "gif."
Raj: What? The guy who invented it says it's "jif."
Howard: I'm sorry, do you mean the guy or the juy?

Sheldon: I'll get the blankets, you Google how to have child-like fun.

Bernadette: Why'd you turn it off?
Sheldon: Because in the last ten minutes, Santa came to town, kissed mommy, and ran grandma over with a reindeer. I had a drunk uncle who did all those things. Nobody sings songs about him.

Penny: Well you wouldn't have asked me either.
Leonard: I would have asked you. In my head. On the way home. While I was having a good cry.

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

Sheldon: Wow, pouting and running away actually worked. I must say that may not be a lesson you want to reinforce with me.

Howard: What are you doing?
Raj: I've created some other user accounts so I can post positive comments about their paper.
Howard: "This wee little bairn of a theory nearly blew my kilt off."
Raj: No, you have to read it like Dr. Angus McDougall of the University of Edinburgh would.
"This wee little bairn of a theory nearly blew my kilt off."

Leonard: It wasn't until his twenty-first birthday that 1955 Biff placed his first bet.
Sheldon: Wow wow wow. Is 'placed' right?
Leonard: What do you mean?
Sheldon: Is 'placed' the right tense for something that would have happened in the future of a past that was affected by something from the future?
Leonard: 'Had will have placed'?
Sheldon: That's my boy.

Amy: That's fascinating. I can't wait to read it.
Sheldon: Oh, me as well. Please email it to [email protected] Why .biz? Because I just gave you the business. And also bazinga.com was taken.

Penny: Hey, I don't think she's wrong about you going too slow in the relationship.
Sheldon: Too slow?
Penny: Yeah, you've been going out for years. You haven't even slept together.
Sheldon: That's right. It's called foreplay.

Amy: Well, you got me something. Here.
Sheldon: Cookies?
Amy: They're your MeeMaw's Christmas cookies. I called and got the recipe.
Sheldon: They're perfect. It tastes like her hugs.
Amy: Merry Christmas, Sheldon.
Sheldon: I can't believe this. You're happy. I'm happy. Maybe a holiday that's all about giving isn't so - Get your hand out of that box!

Amy: It's sweet that you care about him so much.
Sheldon: I do. And I wouldn't be able to forgive myself if something happened to him, and I wasn't at his bedside to say "I told you so".
