  •  
    "Here at BA Central I see a lot of truly ridiculous conspiracy theories. Over the years there's been the Moon Hoax, various asteroids NASA was covering up that would hit the Earth (or wipe us out somehow via electricity), and of course the end of the Earth over and over and over again. Yet happily, we're still here. Yet sadly, so are these silly theories."
