Raj: Yeah, Mrs. Wolowitz was pretty special. When I first moved to America, Howard was my only friend, and she made me feel so welcome in her home. Which says a lot, because those first few years she thought I was the gardener.

Amy: Sheldon, that was beautiful.
Sheldon: If you didn't press record-
Amy: I pressed it!

Howard: Don't feel bad. Some day someone will be throwing out your work, too.
Leonard: That someone was Sheldon and the day was yesterday.

Bernadette: (In pageant video) And you should pick me for Miss. California Quiznos 1999, because I want to tell you what I want, what I really really want. I'll tell you what I want, what I really really want. I wanna. I wanna. I wanna. I wanna, really, really, be the California Quiznos 1999.

Penny: Why are there tears?
Leonard: Everything's fine. We just started talking about living arrangements.
Amy: Are you crazy? You know he's a flight risk!
Sheldon: That's exactly what I told him.

Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.

Sheldon: Is that all you have? Shop-worn tidbits like "talk to her" and "let it go"? Gee, Penny, life's given me lemons, what should I do?
Penny: Well, you could shove them somewhere.

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?

Bernadette: What's happening?
Howard: Raj was snooping through Emily's drawers and broke one.
Bernadette: Oh, I'm gonna miss her.

Penny: You locked them in your basement?
Dr. Lorvis: Well, they're not locked in. The door just sticks.
Penny: Okay, so how do they unstick it?
Dr. Lorvis: They'd need the key.

Amy: Have you made a decision about the TARDIS? I think I can sell it if we call it Big British Portapotty.

Mary Cooper: Well, I would have to say when he was thirteen and he tried to build a nuclear reaction in the tool shed.
Sheldon: Ooh, this is a good one.
Mary Cooper: Now, the first thing you need to know about Shelly is, ever since he was a little boy, he was always concerned with the well-being of others. And he didn't think it was fair for people to pay for electricity, so he was gonna power the entire town for free.
Sheldon: Tell her about the uranium. Tell her about the uranium!
Mary Cooper: Oh, well! Well, this is adorable. When he arranged to get some yellow-cake from Chad, I thought he was talking about twinkies from one of his friends.
Sheldon: Yeah. But I wasn't, because I didn't have any friends.
Mary Cooper: No. It turns out this little scallywag was trying to use my Visa card to buy uranium from an African warlord in the country of Chad.

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 it takes three to five years of shameless begging.
Penny: Honey, neither of us comes off good in that story.

Raj: So, how's it going with the title to the house?
Howard: Great, it's all done. The lawyer tracked down my father and got him to sign it over. I didn't have to meet him, I didn't have to talk to him, I don't even know where he is.
Raj: Wow, so you're not curious at all?
Howard: Nope.
Raj: What if he's in prison? What if he's a spy? What if he's in a Beatles cover band? I'm just saying, if he's got your nose and haircut, he'd make a killer Ringo.

Leonard: We cover ourselves in body paint and then we get on this big canvas and do our thing.
Penny: Woah, that's kind of a big step for a guy who only recently agreed to take his socks off.
