A reference to Danny Elfman of Oingo Boingo fame. Standing near him are fellow band members Samuel Fipps (Sam Phipps), Karrel Grayves (Carl Graves), and Stephen Bhartec (Steve Bartek). One of the major themes invoked by Oingo Boingo was the Mexican Holiday "Dia de los Muertos", the Day of the Dead. During this holiday, Mexicans honor their ancestors by dressing up as skeletons and creating decorations that relate to death. See this, a Wikipedia page for the Oingo Boingo album "Dead Man's Party."
