BBC News likes to post a gallery of photos showing Christmas celebrations around the world, as though humanity is just one big happy Christian family despite embracing hundreds of equally whacky religions and sects. The graphic above is a cropped version from this year's gallery. You might well ask: What does a scowling Bangladeshi fairy having her cheek painted with Santa Claus have to do with that birthday the BBC thinks we're all celebrating? Don't ask me. I'm merely an interested observer of the human fruitcake. Ask Auntie.
