City names
It's so weird how so many states can have cities with the same name. For example, I came across a website for a Morristown personal injury lawyer (I've been playing on Club Bing when I'm bored and it throws up random links) and I automatically assumed it was Morristown, NJ. But it's not. It's Morristown, TN. Everyone knows there are a million Springfields but who knew there were a bunch of Morristowns!
