When I was about 5 or 6, I believed that there was a paintbrush with yellow paint on it underneath our car that would paint the yellow dashes on the road on highways. I searched under our car many times when it was parked, but I never saw any paintbrush or a paint can. This probably came from the fact that I was always stuck in the back of the car on road trips.
