As trivia the cinnamon bun "korvapuusti" literally means "slap on the ear" (but the actual slap is the typical slap in the face, i.e. on the cheek).

Why the bun is called that? Eeh, it's just how things are. Go bother the English about why their completely vegetarian fruitpies have been called "mincemeat" for centuries instead.
