Looks like someone in McDonald's marketing didn't double check their new design before it hit the stores.

Or maybe people just have nothing else better to do.

McDonald's brand new Peppermint Mocha McCafé is causing a bit of a suggestive stir for some budding artists. The new cups bears the seemingly innocent message "Warmest Greetings" over a pair of white mittens with a red background.

But for those with dirty minds the image changes to something more perverted with the simple stroke of a pen or pencil.

Just add some fingers to the thumb of each mitten, and instead of a cheerful holiday message you've got a giant spread butt.

Yeah, there's an obvious bad joke about spreading Christmas cheer, but whatever.

The altered image was first posted on Rebrn, but has since been shared to Reddit and all over the internet.

Here's the official unaltered cup

And here's the updated version
