As the official JJE I use the power of the Jury to decide that everyone is Guilty, The power of the Judge to sentence everyone to death, and the power of Executioner to make it so. Goodnight everyone. One. Last. Time.
listen to these while watching the gif.
edit found a better evil laugh video.
personal favorite evil laugh is admittedly the Wicked Witch. Just such a classic. Though I'd prefer to have the Joker's, Or Jaffar's now THOSE are laughs worthy of Evil.
