From "Stranger Things" episode 2x03. The dialogue went like this:
"Mr. Henderson, you know the rules. Five at a time."
"Yep. One, two, three, four and five."
"Ten. You already have five books checked out."
"My mistake. However... I am on a curiosity voyage, and I need my paddles to travel. These books... These books are my paddles."
(the boys got the curiosity voyage thing from their science teacher who is awesome and enthusiastic)
(with special appearance of librarian Nancy Pearl and some kids from "Gotham")
