They're both set in a post-apocalyptic world populated by a bizarre set of characters, so it makes sense a mashup of Mad Max: Fury Road and the cult television show Adventure Time would make a movie that was totally on-point.
Created by Egor Zhgun, Madventure Time puts the Adventure Time team, from the Earl of Lemongrab to Princess Bubblegum, in the grim, desert world of Mad Max.
Inspired by Ryan May's cartoons -- which turned Adventure Time's Ice King into the Mad Max's villain, Immortan Joe, and Finn into Mad Max himself -- the trailer is almost as good as the original film. The cartoon penguins as War Boys are definitely the best addition, though.
