Amy: Parental pressure can be daunting. I remember the battle with my mother about shaving my legs. Last year, I finally gave in and let her do it.

Amy: You know, the connection between marriage and money is nothing new. In fact, the term wed referred to the money and livestock that the groom paid the bride's father. For example, you're adorable, intelligent and a good earner. I could conservatively see you going for at least two oxen and a goose. (To Penny) You would fetch a unicorn.

Howard: How about Florida? They've got Cape Canaveral, they've got Disney, they've got my Aunt Ida and the world's largest collection of diabetic candy. Plus, if you get sweaty enough, her plastic-covered furniture is like a flume ride.
Sheldon: My family took a trip to Florida when I was a child. A seagull stole a hot dog from me on the beach. I got the message.

Sheldon: It's like I'm living in a dictatorship. You must take a vacation, you must have fun, you must enjoy life.
Howard: I don't think you have a good handle on dictatorships.

Leonard: Sheldon, everybody takes vacations.
Sheldon: One time they tried to make Richard Feynman take a vacation, but he chose instead to expand his mind and learn something new. He went to work in his friends biology lab. Richard Feynman was a famous American physicist, part of the Manhattan Project.
Howard: Everyone in the world of science knows who Richard Feynman was.
Sheldon: Now you do, too.

Sheldon: Oh! I have a brilliant idea. Amy's a biologist. I'll go work in her lab.
Howard: Isn't that just Feynmans idea?
Sheldon: Ten seconds ago, you never heard of him. Now you're an expert.

Leonard: Is that your laundry? You only have, like, six things in there.
Penny: Yeah, I didn't have any quarters, so I've been sneaking stuff into other people's loads all day.

Penny: I think about a lot of things. I think about us getting married, I think about us breaking up. Once in a while, I think about how I didn't leave a note on that Mercedes I dinged in the parking lot last month, but then I have a glass of wine and it passes.

Leonard: Joke all you want, but you think about it.
Penny: Well, tell you one thing, if I ever do get married, no Klingon invitations.
Leonard: Good luck catching a man with that attitude.

Amy: Come on, Sheldon. We can be like Marie Curie and her husband, Pierre, who spent their days working side by side, bathed in the glow of their love and the radium that ultimately killed her. Screw Beauty and the Beast, that's the love story Disney should tell.

Leonard: Where's Howard?
Raj: No hi, Raj? No how are you, Raj? Just straight to where's the other white guy?

Leonard: So, listen, I heard something about him. Can you keep it between us?
Raj: Ooh, gossip. When I first got here, I thought you Americans really gossiped around the water cooler. So I hung out there for, like, a month, but the only gossip I ever heard was about some creepy guy hanging out by the water cooler.

Leonard: Bernadette wants to get a pre-nup.
Raj: Oh, that's a shame, he's gonna be devastated.
Leonard: I never know what to do in these situations. Should I give him a heads-up?
Raj: Hmm. I'm gonna give you the same advice I yell at the TV when the Bachelor's handing out roses. Follow your heart.

Howard: You know what, it's not a big deal. She makes more money than me. She wants to protect her financial interests. It's completely reasonable.
Leonard; Good. That's a healthy attitude.
Howard: Yeah, actually, it's good for both of us. I have assets to protect, too.
Raj: Like what?
Howard: I've got some rare comic books. The Vespa's almost paid off. And Ma and I have a primo double cemetery plot at Mount Sinai right near the guy who played Mr. Roper on Three's Company.
Raj: Mr. Roper's dead? You can't just spring that on a guy.

Sheldon: Those are perfectly clean.
Amy: Sheldon, this beaker used to contain cerebral spinal fluid from an elephant that died of syphilis. If it is, in fact, perfectly clean, drink from it.
