PARIS: I just think it’s strange that you don’t wanna be queen.
RORY: You know, not all girls want to be queen, Paris. Even Barbie ended up being a stewardess.
Rory is referring to the doll named Barbie, previously discussed. One of her early “careers” was becoming a stewardess with American Airlines in 1961, where she wore a uniform and carried a flight bag. Barbie never has been a queen, although since the 1990s she has been a princess.
