Recreate Joker's infamous look by dying your hair green or throwing on a wig. From there, apply white face paint to your whole face. Once that sets, you'll need to add the clown-like details. A large red smile that stretches from cheek to cheek and a red nose are essential, along with blue triangles above and below your eyes. Draw on red eyebrows on the top of your forehead, and get ready to spook all those around you.
