At rise: Kelly is making fun of people who carry around books that they never actually read.

 

Isa: I dunno, I’ve been carrying around this book about Cesar Chavez for a couple months.

 

Kelly: Why haven’t you read it? You can find out about how he tried to kill your grandfather!

 

(Long pause.)

Isa: Um… you mean Fidel Castro?

 

Kelly: Oh, right. Different guy.
