In this week’s Flightless Bird, David Farrier sets to understand where the heck Halloween came from, a holiday which generates over $10 billion in retails sales in the US each year. Why does an average American spend $60 on the scary day, and is it more tied in with paganism, Christianity, or scary monsters? David meets with Regina Hansen - a writer and scholar who teaches at Boston University - to talk about why we used to carve turnips instead of pumpkins, before calling up professor of philosophy and religion Justin Sledge to talk horror movies. Finally, David decides to use the spooky season to try and communicate with a ghost that’s been waking him up every morning at 3am.
