The Festival of Books is an outdoor book fair in Springfield.
Famous authors such as Stephen King, Tom Wolfe, Tom Clancy, Maya Angelou, John Updike and Amy Tan appeared at the festival, signing books and giving talks.
Krusty the Clown also signed copies of his children's book Your Shoes' Too Big to Kickbox God, and Christopher Walken read Goodnight Moon to children.
In Insane Clown Poppy, the Simpson family went there to celebrate Lisa’s birthday after Homer accidentally destroyed her room with fireworks. At the festival, Krusty the Clown met his daughter Sophie for the first time, who was the result of a one-night stand with a soldier during the Gulf War.
