Sheldon: This place could really use a suggestion box.

Howard: I haven't seen him laugh that hard since the day Leonard made that multiplication error.
Sheldon: Oh, Oh, Lord, that multiplication error! He thought he carried the one. But he didn't.
Leonard: It's not funny. That mistake got published.
Sheldon: Stop! I'm going to wet myself!

Leonard: Lobster traps?
Sheldon: Yes. That's how Velma and Scooby smuggled Shaggy into the old lighthouse.

Raj: Hey, guys, guys, President Siebert is headed this way.
Howard: I wonder what he wants.
Leonard: Doesn't look happy, so I'm guessing he wants to talk to Sheldon.
President Siebert: Dr. Cooper?
Leonard: Told ya.

Sheldon: Oh, President Siebert, I assume you'd like to respond to one of the suggestions I put in the box by your office.
President Siebert: No, and stop installing suggestion boxes everywhere.
Sheldon: You don't like written suggestions. You don't like when I give them to you while we're urinating in the men's room. If I didn't know any better, I'd say that you're one of those stubborn people who are not open to suggestions.

President Siebert: Dr. Cooper, the physics department chair tells me you're refusing to take your vacation.
Sheldon: I don't need a vacation.
President Siebert: You're obligated to take one. And I'd also like you to know the most-often received suggestion in my suggestion box you installed without asking me is can Dr. Cooper take a vacation?

Penny: I'm so glad you talked Howard out of having your wedding invitations in Klingon.
Bernadette: Turn it over. I'm hoping my relatives think it's Hebrew.

Amy: This is really happening. I'm gonna be a maid of honour. I'm gonna wear a beautiful dress and walk down that aisle and, finally, I will have my special day.
Bernadette: You mean my special day?
Amy: They're gonna need an extra-large veil for somebody's head.

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.
