A black cat and the number 13 - How unlucky can you get? Searching for clues is a bitch! Sometimes, you don't even know what you're looking for. Most of the time, thats because the very thing you are searching for is unavailable. Did you know that most buildings are missing the 13th floor? And most department stores don't have a 13th isle. Is that because it's unlucky? Or because it's too lucky? People are too superstitious. Even though you see floor 12 and then floor 14 in an elevator, it doesn't mean that the 13th floor doesn't exist. It was just wrongly named. If you are looking for the 13th video of a Black Cat, should you be worried?
