Welcome To Show! The Dark Knight Devo | October 8, 2019 Deviants, Welcome 2 Show! As we prepare for Joaquin Phoenix to take over the role of the Joker in DC’s weird, new movie universe, we watched The Dark Knight in all of Heath Ledger’s Joker goodness. Devo Devo thoroughly enjoys saying things just to get a reaction out of someone – no matter how absurd the content. Luckily, this has yet to get him into trouble. He’ll end up talking a lot about hockey, Star Wars, gaming and professional wrestling.
