The clip features the Joker showing his true colors in a guest appearance on The Dave Endochrine Show. Michael Emerson (Lost, Person of Interest) offers the hauntingly casual voice of Joker; real-life talk show host Conan O’Brien provides the voice of Dave Endochrine; and Michael McKean (This is Spinal Tap) is the voice of Dr. Wolper.
