Penny: What is the truth?
Sheldon: My Mr. Spock doll came to me in a dream and forced me to open it. And when the toy broke I switched it for yours. Later, he encouraged me to do the right thing and I defied him. And then I was attacked by a Gorn.
Leonard: Okay, that I believe.

Leonard: Once you open the box, it loses it's value.
Penny: Yeah, yeah. My mom gave me the same lecture about my virginity. I gotta tell you, it was a lot more fun taking it out and playing with it.

Leonard: You went to the comic book store by yourself?
Penny: Yeah. It was fun. I walked in and two different guys got asthma attacks. Felt pretty good.

Sheldon: Is the whip sound app contextually appropriate here?
Leonard: Uh, it is, but I think you might have waited too long for it to be funny.
[whip cracks]
Leonard: [Everyone laughs] I was wrong; it was still funny.

Hmm, if it's yogurt that helps ladies poop, I think Raj beat you to it.

Leonard: We're always the good guys. In D&D, we're lawful good. In City of Heroes, we're the heroes. In Grand Theft Auto, we pay the prostitutes promptly and never hit them with a bat.
Sheldon: Those women are prostitutes? You said they were raising money for stem cell research.

I'd make fun of Sheldon for having girl problems, if I wasn't shocked that Sheldon has girl problems.

Leonard: We'll miss you Sheldon.
Sheldon: Yeah, well, who wants to spend the whole weekend, running around a bunch of pretend planets, battling made up monsters? That's for babies.
Howard: Yeah, but it's got lightsabers.
Sheldon: Please, Amy! It's got lightsabers!

Leonard: It will be like our World of Warcraft party a few years ago when the neighbors called the cops on us.
Howard: They called the cops because of the smell. They thought we were dead.
Raj: We were badass back in the day.
Leonard: All right, let's do it.
Howard: 48 hours of Star Wars gaming.
Raj: It's on like Alderaan.

Raj: Hey, want to spend some time playing the new Star Wars game this weekend?
Leonard: Oh, I don't know. I kinda promised myself I'd get off the computer, be more physically active, get some exercise....?
Howard: You're about to walk up three flights of stairs.
Leonard: Good point. I'm in.

Penny: Why did you get bongos?
Sheldon: Richard Feynman played bongos, I thought I would give that a try
Leonard: Richard Feynman was a physicist
Penny: It's three o'clock in the morning, I don't care if Richard Feynman was a purple leprechaun that lived in my butt!

Penny: Ok, what just happened?
Leonard: I don't know. Between you playing chess like Bobby Fischer, and Sheldon being ok with you in his spot, I'm guessing someone went back in time and changed the course of human events.

TBBT Quotes

Leonard: Hi. I'm Leonard. You are beautiful. You pop, sparkle and buzz electric. I'm going to pick you up at eight, show you a night you will never forget.
Raj: Where are we going?

Penny, there's only one cookie with something in the middle that solves life's problems, and that's an Oreo. Or a Nutter Butter, if you're in a pinch.
