Sinatra later appears in the Season Seven episode, "Cancelled", as one of the forms Najix takes in his effort to appear familiar to the boys. In "Hell on Earth 2006", Satan says hello to an off-screen Sinatra at his party.
In "Do the Handicapped Go to Hell?", Sinatra appeared with a real-life photographic cutout as a head, much as many other celebrities did in the earlier seasons. In "Cancelled", he appeared like other South Park characters.
