Sheldon: So, Dr. Wolcott, in your letter, you said you had a new mathematical approach that would help me conceptualize the dimensions in string theory?
Doctor Wolcott: Uh, yes, yes, yes, yes. But before we get started, I am going to need to collect everybody's phone. Yeah.
Sheldon: Oh.
Leonard: Why?
Doctor Wolcott: Because they're little listening devices, aren't they? Yes, for people to spy on you and steal your work.
Howard: Yeah, what happened to the good old days where if someone wanted to steal your work, they had to hire a prostitute to seduce you?
Doctor Wolcott: Who told you about that?
Howard: Just making a joke.
Doctor Wolcott: Yeah, it's not funny when it happens.
