Howard: Sorry, it's just the director of the planetarium thought it'd be fun for me to join Raj for one of his shows, and he made it clear that he didn't want me to.
Bernadette: Of course he wouldn't want you to. I mean, think about it. If you were him, would you want to share the stage with a sexy-ass astronaut?
Howard: I don't know. How sexy are we talking?
Bernadette: Oh, you know, tight pants, huge biceps, magic hammer.
Howard: Wait, who are we talk-
Bernadette: Shh, I'm back in it.
