Raj: Well, that's the lecture for today. Uh, let's open it up for questions. Uh- Oh, you! Sir, yes. You have a question?
Howard: Yeah. Actually, I have a two-part question.
Raj: Are you sure? I get the sense it's only one part.
Howard: No, no, it's two. Part one: the new star you were talking about. How long did it take that light to reach Earth? And part two: is it true you plant your friends in the audience to ask questions?
Raj: 46,000 years. And no, I don't plant my friends, because apparently, I don't have any.
