These kinds of pictures always freak me out!

No, this girl's arm is NOT 6 feet long. It's an optical illusion caused by the perfect positioning of people, their clothes, and a furry coat. The picture is blowing up the internet. Thankfully, The Huffington Post talked about it some more, and this Twitter user put up this picture to help sort it out.

If you have a picture you've taken that has a weird optical illusion, I'd love to see it. Just post it in the comments section.
