It's not pranksters or vandals who placed toilet paper all over the streets of Littleton, Colorado, it was city workers.
The Denver Post reports that Littleton crews have used bathroom tissue to help seal up cracks along more than 120 streets.
Officials say toilet paper was applied with a paint roller over freshly laid tar used to fill asphalt cracks. The paper absorbs the oil from the tar as it dries, keeping it from sticking to pedestrian's shoes or car and bike tires. The biodegradable paper will break down and be gone in a few days.
Littleton spokeswoman Kelli Narde says the toilet paper allows traffic to retake the road more quickly.
