Trivia
In City of Thieves, Finn was originally going to proclaim he and Jake were virgins, which was edited by network standards to "virgin islands".

In Wizard, Finn and the Old Wizards were originally going to have their nudity covered with a beaver, but network standards changed it to a log.

In Tree Trunks, network standards added in a scene of Tree Trunks (character) walking in front of a background of said to be the Crystal Gem Apple because just having her explode was considered "too dark".
