Just Another Brick in the Wall?

This seemingly harmless image displays a shallow-angled brick wall with noticeable gaps between the bricks. Red bricks appear to have a little grey pebble wedged in between them right above the centre. It appears to be a cigar that has become stuck to the wall. Although it really protrudes at a 90° angle, the photo was composed such that the cigar’s body lined up with a gap in the bricks. The cigar seems to be the space between the bricks, and the ash at the end appears to be a rock wedged in the gap in addition to the cigar being black.
