Leonard: This... is exciting. This is really exciting. I have to go find Sheldon.
Penny: Okay, well, if you find him, use the kitchen island- that coffee table will not support both of you.

Leonard: You're giving me a sticker?
Sheldon: Not just a sticker. That is a sticker of a kitty saying, "Me-wow!"
Leonard: I'm not a preschooler.
Sheldon: Fine, I'll take it back
Leonard: I earned this! Back off!

Leonard: You wrote a paper on my idea?
Sheldon: I wrote a paper on our idea.
Leonard: When did my idea become our idea?
Sheldon: When I mixed it with Sheldony goodness and cooked it in the Easy-Bake Oven of my mind.
Leonard: This is good. Our idea is really good.
Sheldon: Well, the light bulb in this oven is ridiculously bright.

Leonard: You're sure it's good?
Sheldon: My name is right on there with yours. That is a surefire
mark of quality. That might as well say "Directed by Joss Whedon".
Leonard: Okay, partner, let's do it.

Leonard: Uh, another one says, "The concept shows some real out-of-the-box thinking".
Sheldon: Do you hear that, Mr. Out-Of-The?
Leonard: I do, indeed, Mr. Box-Thinking.

Raj: The guy who plays Jon Snow was a jerk and we still watch Game of Thrones.
Leonard: He was a jerk because you rear-ended him.
Raj: I was distracted. It's weird seeing a member of the Night's Watch with kayak strapped to his car.

Sheldon: I didn't care for her yelling, but now that I'm not going to hear it again, I'm sad.
Leonard: If you want, I can yell at you later.
Sheldon: It won't be as good.

Let's have a toast. To Mrs. Wolowitz. A loving mother ... to all of us. We'll miss you.

Nathan Fillion: How about a guy who looks like Nathan Fillion, but a little more annoyed than Nathan Fillion usually is?
Leonard: What do you think?
Raj: Aww. That's good enough for Facebook.

Amy: I just read about an experiment designed to see if you can make two people fall in love in a matter of hours.
Leonard: That doesn't sound right. My research has shown that it takes three to five years of shameless begging.

Leonard: I'm telling you, you can't create love in a few hours. Right?
Penny: Careful. You're poking at the whole foundation of The Bachelor.

Leonard: And we weren't even watching TV! We were watching Netflix like the kids do!
Penny: Yeah! Is it a comedy? Is it a drama? Nobody knows!

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
