T-Rex: Sometimes when you knock down a wall in old European houses - dating from the 1300s and for several centuries after - you find an old shoe!

T-Rex: AND NOBODY KNOWS WHY.

T-Rex: Clearly they were put there intentionally, but their locations range: under the floor, in the roof, in chimneys, around doors, or even buried in the foundation! There's obviously a tradition of hiding a single shoe in a building - to ward off ghosts? To attract BETTER ghosts with the gift of used shoes? - but the once-widespread tradition died off without anyone recording WHY they did this, and now we just don't know.

Utahraptor: Nobody wrote it down?
T-Rex: Not in any book that survived!

T-Rex: So all we have now are weird ancient surprise shoes that show up sometimes: a reminder that the past is a foreign country - and not only did they do things differently there, they did them for private, inscrutable reasons that are forever and completely beyond us.
Utahraptor: Huh.
T-Rex: Yeah.

T-Rex: Anyway! It's Hallowe'en, and I'M off to carve a terrifying face into an orange gourd, start a small fire inside it, and leave it to rot outside my house for a few weeks, as is the tradition of my people.
T-Rex: No, I will not be taking questions at this time.
