Kev (The Halloween Apocalypse)

Kev, a drunk, knocked on Dan Lewis's door on Halloween shortly after he gave sweets to a trio of kids in costumes. Unlike them, Kev was not only too old to trick-or-treat, but isn't even wearing a costume, though he did carry a carton of eggs to show at people's houses. He blithely demanded of Dan that he give him sweets as well, which Dan refused to do, also warning Kev not to throw any eggs at his house. Shortly after Kev's departure, Dan received a third visit, this time from Karvanista. (TV: The Halloween Apocalypse)
