Quote from Amy Farrah Fowler in the episode Spoiler: Stuart Makes a Wallet
Amy Farrah Fowler: Okay, uh, here's what we're gonna do. Let's keep your Shamoxil where it is, and I'm going to double your dosage on Trafederine, see if that doesn't help. Stuart: You think I'm crazy? Amy Farrah Fowler: Oh... That's not a word we like to use around here, but... [grimaces] Stuart: Doesn't matter. I... gotta get out of this place. Amy Farrah Fowler: To go to a different universe? Stuart: Not just different, a good universe. You know, without giant moths, or evil demons. Amy Farrah Fowler: Right, sure. Well, if you make progress, it's not out of the question that someday you can leave. Stuart: Someday? What... what... what does "someday" mean? Amy Farrah Fowler: It means a vague time in an unspecified future. Stuart: That sounds like never to me. Amy Farrah Fowler: Oh, "never" is not a word we use around here. It can be upsetting.
