In S1E10, Rory is telling Lane about all the Christmas gifts she bought for people. When Rory says that she got Dean a book, Lane interrupts, “You got Dean a book?” Rory says, “Yeah, ‘Metamorphosis.'” Lane goes on to refer to the book as “a really confusing Czechoslovakian novel” and (metaphorically) as “a Czechoslovakian football.”
“The Metamorphosis” is a short novel by Franz Kafka, published in in 1915. The story is about one man’s adjustment to life as a monster.
Kafka was a German writer who was born in the Kingdom of Bohemia, which later became Czechoslovakia. In 1993 Czechoslovakia split into two separate countries- the Czech Republic and Slovakia.
