Jane Austen's Mafia!

"The riddle at the start of the film is wrong. The riddle asks, "If a rooster were to lay an egg on the roof of a pen, which side will it roll down?" The given answer is "Roosters do not lay eggs." But given the fact that in the question, it tells you straight that the rooster already laid the egg. So even if the rooster laid the hypothetical egg, would the answer still be "roosters don't lay eggs?" If you watched that roosters egg fall down onto the floor, would the answer to that riddle be "roosters don't lay eggs"? I believe not!"
