Certain people like to say you are what you eat, but I feel like a lot more of us can get behind that we are what we wear. Our clothes are one of the main things that send out a message about who we are to all those around us, even if we don't care much for being stylish. Whether we like it or not, we're likely to be judged on what we wear, so we may as well have fun with it.
One of the most obvious ways to do this is through a classic slogan t-shirt. You can't get more obvious than slapping a philosophy across your chest, the stupider the better. Over the years, this kind of garment has become something close to an art form: and boy, are there some weird ones out there. You might get weird looks sporting some of these examples in public, but a lot of them are kind of cool.
