This Brick Wall Optical Illusion Will Make You Go INSANE

This may look like an ordinary brick wall, but it's not . . . When Manchester, UK, Facebook user Arron Bevin posted this photo, the internet flipped out. There's an optical illusion in this picture that some people see right away, while others find it totally impossible to figure out. Are you able to see what everybody is going crazy about?

Once you figure this out, you won't be able to unsee it — we promise. Let's see how long it takes!

There's a cigar wedged into the crack of two bricks toward the right side of the photo. That gray hole you see is the end of the cigar. Can you see it now?!
