Sometimes things happen that you can't explain. Some might call these paranormal experiences. You see something move in the middle of the night that's not supposed to move. You see a shadowy figure slink across the room that you can't identify. You see a light in the sky that doesn't quite seem like an airplane. These incidents occupy our minds and we have no way to fit them into our logical conception of the world. They just have to exist on the margins of your memory, not sure if they're real or they're fake or they're some mystical intervention.
These design fails are sort of like that. You can't quite imagine how they came to exist. You can't conceive of them as real. But I'm here to tell you that they are. They're real. And they can't hurt you. They can only make you laugh. But who knows, maybe there is something supernatural at play here.
