As Christmas Jumper Day takes hold across the UK, one mum has shared a cautionary tale for paying close attention to the outfit you chose.
The mother, with the username Angryhamzter on photo sharing site imgur, posted a pic of her son proudly displaying his jumper before heading off to nursery school.

On it Santa appears to be urinating the words 'Merry Christmas' onto the snow.
