A ha! He's a Hurricane

Most times we'll have plenty of notice for a hurricane because it will storm in right off the sea. Sometimes, though, it will sneak in wearing a hat and a trench coat. If you see someone in a hat and a trench coat, pull them off and shout, "Aha! A hurricane!" Most of the time, it will actually be some guy and you'll look pretty stupid, but, if one time it actually is a hurricane, people will be like, "Wow! You're smart."
