LONDON -- Ah,Taste of a Married Woman the holidays. They just wouldn't be the same without the bustle of Yuletide shopping, sweet mince pies and holiday cups full of steaming hot drinks.

This year's McDonald's holiday cup is festooned with cosy mittens, snowflakes and stars. It's a scene of Christmas innocence that'll warm the cockles of your heart.

Except, someone went ahead and ruined it.

The mittens could've been left alone, but someone decided to make a subtle change that transformed this cup into something very, very, very NSFW. With the simple addition of two hands, these lovely mittens have been altered to look like a butt.
