Sheldon: You know, in fact, I'd like to propose a toast. To Stuart. A fine man, a good friend and a wonderful guest.
Bert: Hear, hear.
Amy: Cheers.
Mrs. Petrescu: Cheers. Filmed before a live studio audience.

Guy: I didn't know you can propose to the same person so many times.
Leonard: The third time, I did it in skywriting, but she never looked up.
Penny: You know, once, I proposed to him.
Leonard: Yeah. I said no.
Guy #2: Why?
Leonard: I just wanted to make her work for it.
Penny: Yeah, that's gonna cost you later.

Daniel: I love your movie.
Penny: Well, thanks.
Daniel: It has got to be one of the worst things I've ever seen in my life.
Penny: Your love confuses me.
Leonard: Would you like an autograph?
Daniel: Sure.
Penny: Okay, who do I make it out to?
Daniel: Daniel.
Penny: Okay.
Daniel: I have to ask. Were you trying to be that bad, or are you just a terrible actress?
Penny: That did not clear things up.

Amy: Maybe I can get a little help putting some of this stuff away.
Sheldon: Oh, calm down. I already put away five of these (Mimosas)! (To Stuart) You see? No muss, no fuss, not a single cuss.
