Only One Day Late

In "Sgt. Gravel to the Rescue" from "PB&J Otter," when his library book is late, Peanut Otter has an Imagine Spot in which he finds himself in the lower decks of the book boat, which is now a prison barge. An otter who looks like an elderly version of himself asks what he's in for and he tells him it was an overdue library book, but it was only one day late. This gets a good laugh from the elderly otter and the other prisoners, who have heard this excuse before.
