Just for the heck of it, I thought I'd do a fact check. I heard that during the 1904 St. Louis World'f Fair, one of the tribes were eating the neighborhood dogs. True they were eating dogs, but they weren't stealing them. They were made to eat them to shock fair goers to their customs.

I thought I'd be able to show that one time in history it did happen that pets came up missing but ... never mind.
