There are a lot of really helpful signs in the world. Without them, we'd get lost, get injured, and even have problems opening doors. Admit it. You've pushed when you should have pulled more times than you can count. Point is, the world needs signs. No one would know how to do anything without them. Then there are these funny signs. These are signs that are so helpful, they're really not even necessary at all. Some might call them silly or weird, but really they're just awesome. These signs don't have to exist, but they do. And the world is a better place for it.
