RORY: You did it [the chalk outline]. The whole town knows you did it. They had a meeting about it.
JESS: You actually went to that bizarro town meeting? Those things are so To Kill a Mockingbird.
To Kill a Mockingbird, the 1960 novel by American author Harper Lee, previously mentioned. The novel is set in the fictional Alabama town of Maycomb during the Great Depression, and focuses on small town prejudices, traditions, and taboos. The book made an immediate sensation on publication, won the Pulitzer Prize, and became a bestseller. One of America’s most beloved novels (and a great favourite worldwide), it is often set as a text in high schools.
Note that Jess uses the word “bizarro”, just as Lorelai has done.
