Quote from Amy Farrah Fowler in the episode Spoiler: We Couldn't Get Green Lantern
Amy Farrah Fowler: [opens door] Can I help you? Stuart: Amy? Amy Farrah Fowler: Yes? Stuart: Is this the Garrick residence? Amy Farrah Fowler: Yes. Stuart: Uh, I'm... I'm confused. Jay Garrick's girlfriend is Joan. Amy Farrah Fowler: [scoffs] Joan. Joan took her Subaru and headed to Portland, if you know what I mean.
