Favourite Chick tract? My fave is the one about the Christian Rock band who are transformed by Lucifer and rock music into gays, vampires, and satanists.
While there are classics like Boo! and The Devil’s Night about the dangers of Halloween, Dark Dungeons about the dangers of role playing games, The Death Cookie about the dangers of Catholic eucharist, Hi There! about how you are definitely going to Hell (not a joke: adapted “for black audiences” as Wassup?), or The Nervous Witch about the dangers of Harry Potter, my favorite is probably Mama’s Girls, which is about how the pope invented Muslims, Freemasons, Nazis, and Communism.
