In "A Corpse in My Bed", Erik was originally gonna die and it'll be his final appearance because of it. Thankfully, Michelle Ziliak changed the ending instead; which is a good thing cause otherwise, it'll be much worse.
Music
While "A Gorey Demise" is a darkly funny song at the most part, most of the deaths are rather realistic and pretty depressing, and may bring bad memories to the sensitive.
G is for Greg, who died in the womb.
Being based around real-life witch trials, brutal murders of innocent people, and having a tone more somber than the rest of their songs, "Here There Be Witches" is quite tearjerking all of its own.
