In this episode we learn that Grace's office is located in the Puck Building at 295 Lafayette St., south of Houston St.
Grace bemoans the fact that an image in a cosmetics line of a "Jennifer-Love-Michelle-Sarah-Felicity-looking thing" triggered her insecurities. She's actually referring to then-young stars Jennifer Love Hewitt, Sarah Michelle Gellar and the star of Felicity (1998), Keri Russell.
